The trend nowadays seems to be for everyone to ask for tips. I guess I kinda understand as it costs them nothing to do so and they definitely don't lose anything (and only serve to gain) by asking / soliciting for tips.
They don't lose anything in the short term, but look what tipping did to the restaurant industry in the long term. As tips become standard, businesses use them as a reason to keep wages low - in some cases lower than minimum wage.
