You understand completely. I’ll bet you did a great job. If you do your job well and consistently, you make out.
Not only you, but your employer. People DO go to places for great service...granted, if the product isn’t great, service generally isn’t going to cover that flaw. But if things are anywhere near each other in product quality, service wins out.
As we left, I was last f-i-l in front of me. We passed the waiter, who held the tip tray out (the bills were spread, like a poker hand) and he said:
"Sir? I believe you may have made an error..." (as he said this he tapped the bills)
f-i-l w/o missing a beat said:
"Oh, I think you are right. Thank you for telling me."
He then reached out and took a 20 from the tray (the service had been terrible).
