For some people with epilepsy, caffeine is a seizure trigger. Ordering a decaf and having a seizure because some idiot doesn't follow the rules not only would ruin someone's day, but could be life threatening.

Or for many people who like the flavour, but getting the actual caffeine guarantees a sleepless night, and lots of stressful work consequences from not having slept and no time next days to make that up.

I have caffeine sensitivity - makes me feel very weak and shaky. Don't want that to happen when driving. I need the correct drink. https://www.caffeineinformer.com/caffeine-sensitivity

That really sucks to hear! Sometimes it helps telling them friendly why it has to be decaf, other times people react like you are just making up excuses, it's really annoying. Had the same done to me with a juice, when I told them I was allergic to kiwi. They didn't believe it. The juice I was given had kiwi in it and I had an allergic reaction that lasted for hours. =(

i have 3 different types of anxeity disorders general, social and trauma anxeity. caffine im fine with unless i have too much, if i have too much ill get an anxeity spike but i wont have a panic attack my brain will just b on overdrive remembering all mistakes ive made in life and hoping they dont effect my happy life now etc. only caffine i can have endless amounts of is from tea idk y mayb the tea has calming enough effects that the caffine doesnt effect me like coffee does. but anyways i had my caffine fill for the day but wanted pumpkin spice coffee i ordered decaf they gave me regular and i was in the corner of starbucks muttering to myself thankfully my friend was working that day so he explained to everyone wat was going on that i wasnt crazy etc. the girl who served me was fired bc apparently my friend even told her to make sure its decaf so she was told but she clearly didnt and put me in a state of panic and fear. this was before i met my husband so i was even worse back then. the manager let my friend leave work early so he could take care of me. he brought me to his house, sat me down in the recliner, got his dog and put him in my lap and waited. after 15min of having a little floofball licking my face and snuggling my face i calmed down. only thing he said to me was "i kno albert isnt brandy but i figured they r the same size and both fluffy so he might b able to help too" all my friends knew brandy my dog was the cure to my anxeity and since my friends house was closer he did the first thing he could think of that would help. i was able to tell it wasnt brandy but it did help. point is if u work in the food or drink industry always do as the customer says even if its an annoyingly long complex order for all u kno it can b that way for health reasons

The last time I ordered coffee out, I ordered a decaf iced coffee. The cup was marked decaf, but I had severe anxiety like an hour later. I was out shopping with family, and felt so bad I had to go sit in the car. Haven't been back there since.

Coffee makes me sick. Decaf or regular. There are only a handful of coffees I can actually drink and I can't have it every day. The oddest part: espresso does not have the same effect on me. Why? I have no clue.

I don' drink coffee for religious reasons (caf or decaf) and I try to avoid caffeine for ADHD reasons (don't think it affects me like it affects others but still). I always specify no coffee when i order something like a frappichino as a drink and luckily I've never had a problem (not to mention I could probably tell if they put coffee in something or at least i hope i could). Also turns out their refresher drinks have green coffee beans in them and are in fact caffeinated which i did not know for a long time until i looked on their site even tho i asked the barista if they contained caffeine or coffee and i recall them saying no.
