The slowness kills me. I worked for a coffee place in downtown Pittsburgh most summers/Christmas breaks over college and we hussled. I remember working conventions with me and a manager and everyone saying how fast that long line moved compared to upstairs vendors who had way more people working. I was taught to move quickly and get thru morning rush ASAP as that meant more customers served and more tips. We sometimes might have moved too quickly and pulled the grinds before it was done brewing, but hey we at least never ran into each other while holding a carafe of coffee
But I also can't stand their burnt coffee, it isn't good. Which also might be a byproduct at working at a place that got coffee from a roaster downtown and then grinded it. We were serving coffee that was roasted that week and grinded that morning. I mean you can't beat that. I am not even a coffee person but can taste bad/burnt over good.
I just never drink coffee on vacation. If I need caffeine I buy ice tea.
