Why should these people, who probably get up when certain college students go to bed, be so kindly? How do they stay so friendly well into the day? After all, if my conjecture that their employer grants them unlimited coffee and coffee products is correct, they are probably fully caffeinated for a couple hours, but then, if they're like me, they start to crash towards the end of the morning. And why should these people be particularly friendly? They have their share of prickly customers, not uncommon among the people who can afford to get a 3.00+ warm beverage every morning demographic.
So my hats off to all coffee shop employees. Keep on doing what you're doing if you feel like it, but don't worry if you're ever in a bad mood. I'll understand.
