I get annoyed by the places that ask for a tip when you walk up to order and pay. I don’t mind tipping a waiter, but why am I supposed to tip someone standing at a cash register?
Yeah that's a tough one. Not only because they aren't really serving/waiting, but they are likely making minimum wage or higher vs. reduced like a server.
I have on a few occasions, tipped at the drive thru window at a local Asian place. Only because the two servers that prepare my order are usually good to me and hook me up, leaving out some things I don't want, and loading up on other things I do.
Other than that, I'll never tip at a drive thru that I can imagine.
On the road the other morning, I was pulling into McD for a coffee. Line was all the way around the building, and out in the highway. Almost passed it up, but next stop was a long way. So I squoze past, and grabbed a parking spot.
Went in... crickets. 2 people in the whole place sitting down. 3 staff waiting at the registers.
Got coffee, pulled out before the next car moved ahead.
That's kind of what it's come to these days. They may need to re-design and add another window. Sad to see the drive thru staff busting azz and the 3 at the registers yawning.
