1. The Chatty Senior
We love our grandparents, because they're family, but getting locked into conversation with a senior citizen stranger is less than ideal.
2. The Friendly Regular
When you go to the same coffee place every day, you'll see the other regulars. They will catch the barista up on all the latest gossip while 10 people are still waiting to make their orders.
3. The Stressed Parent
Children don't really care that it's nearly impossible to juggle a coffee order with a screaming child, and they will make the entire experience as difficult as possible for their parents and everyone else involved.
4. The High-Maintenance Customer
Yes, there are an infinite number of combinations when you order your coffee, but if your coffee order takes longer than five seconds, you're probably a terrible person. You're stressing out the barista, and worse, you're holding up the line.
5. The Office Bitch
Sometimes making your new employers happy means getting a whole lot of coffee for the office. The only real way around this is calling ahead, and that's still bound to be an issue.
6. The Uncertain Cardholder
After the holidays, a bunch of gift card receivers head in to the café to cash in on their presents. The problem is that they've got pockets full of gift cards and no idea how much money is on each.
7. The Cautious Dieter
Another post-holiday tradition — trying to lose weight. However admirable, this is usually a headache for everyone else, and anyone on a diet is going to spend far too long calculating the calories of their skinny vanilla latte and blueberry muffin. (Hint: skip the muffin.)
8. The Undercaffeinated Addict
Caffeine withdrawal is rough, which is why you should always steer clear of anyone in need of a coffee boost. Coffee addicts tend to be grumpy, agitated, and sometimes too groggy to make a simple decision.
