If it's not an expectation now, it will be soon. Tipping became a thing partly because managers started telling their employees to start asking for tips, and soon enough it became effectively mandatory. It's better to just not have things set up to create the problem in the first place. I don't really want waiting staff or taxi drivers forced to coerce tips out of me.
