Working as a barista was the hardest and most stressful job I ever had, and some of these I wish I had the balls to do when I was treated poorly by customers, but I never could. Let’s be honest with ourselves though, we all knew that things like this happen behind the bar in coffee shops, just like they do in the restaurant business, retail, and everywhere else that customer service is a huge portion of the job. You lose faith in humanity some days. The expectations people have on baristas to do a 5 star job for a drink they paid $5 for is ridiculous. No one seems to realize that a barista job is a minimum wage entry level fast food job, not the Ritz-Carlton. Baristas are on their feet for 8 hours straight, for me I sometimes had to work almost 16 hour shifts, and customers don’t realize how overworked and exhausted we are! Your batista TRULY hates you if they’ve been behind the counter long enough. Anyone who doesn’t is still naive.
