I do not like charbucks but sometimes it has been the only option. I have NEVER encountered anything but courteous behavior from the coffee clerks there. And I have been to literally thousands (tens of thousands) of places where there is a tip jar and NEVER ONCE has its existence been even pointed out by the people serving me.
Interesting how DUmmies bring the worst out of people.
I will bet anyone that this is how a conversation probably went:
"What's this? Free money?"
"No, DUmmy, it's a tip jar."
"Are you sure it's not for Muscular Dystrophy, and you're stealing donations?"
"No, it's a tip jar for people to leave tips."
"Am I SUPPOSED to leave a tip?"
"No, as with any opportunity to tip, it's strictly voluntary."
"Well, I don't want to tip you."
"Then don't leave a tip."
"How many people leave tips?"
"I really don't know."
"But enough. Are you paid a living wage?"
"Starbucks actually provides a lot of benefits to us, even part-timers."
"So why do you need tips?"
"Again, tips are strictly voluntary. You don't have to leave one."
"Well, frankly, I don't want to leave you a tip. In fact, I might like for you to tip me for coming here."
"Oh, I see: you're a *******ed lunatic. I have actual customers to serve. Please leave the store now."
"Damned FASCIST! I'm telling the internet on you!"
"Can you please leave? I think you're about to crap your pants and I don't need that in my store."
"Too late!"
