... and everyone should have to drive across the US at least once to earn the right to make a flight on an airline.
What I think is acceptable about tipping when there is very personalized service
... well beyond the Standard Operating Procedures.
But it seems to be our way of life in the US when it comes to food.
If it's just a matter of taking your order and delivering the plate and drink to your table, that's S.O.P.
e.g., Should "servers" making sub-sandwiches for the conglomerate Subway get a tip ?
It's highly personalized service to make each sub just the way you want it.
But it is rare, if not ever, that I see them being given a tip.
... and Subway's are an even more personalized service than the "golden arches"
The whole business of tipping as S.O.P. for food service does not work for me.
And yes, I do tip when it's not S.O.P. and/or someone has done something beyond their usual call-of-duty.
