TIPS were to insure proper service...
perhaps asking before delivering is acceptable.
I thought tips were to show appreciation for great service and one is never obligated to tip. It does show ones character if they wont tip when deserved.
When I call for delivery, I ask them to add the tip to the bill in advance. Much easier that way.
“TIPS were to insure proper service...perhaps asking before delivering is acceptable.”
Then build it into the price, like most countries do.
Now with waiters making $20+ per hour (more than twice what they made just 5 years ago), they already have their ‘tip’ as far as I’m concerned.
