danny, you choose to call it a "gift" that cannot be earned.
Many think of it traditionally as a Christmas tip.
A tip should certainly be earned and deserved, but as I already mentioned does not make it mandatory.
"But of course, being employed inside, you would not know about that?"
That is either silly or stupid and I could use the same reasoning on you as you don't work at all for UPS.
I was a driver for sixteen years and received many tangible shows of appreciation (whatever you want to call them) during the Christmas seasons during those years and since for that matter.
The fact is, you show you don't know what you are talking about by mentioning the inside factor in this regard.
The counter has regular customers just like the drivers and many of them show their appreciation in the same way customers do to their drivers.
After all, it's basically the same thing, we supply a service that we are well compensated for and some customers appreciate it more than others and choose to show it by giving us something during the Christmas season.
You are welcome UPSmeoff,
The fact is danny who has very strong personal opinions and states them prolifically, but that does not make him the official judge to pontificate any moral judgements on your pleasure in this seasonal tradition.
