Earlier quoted context omitted.
Yeah, there is a lot of shadiness going on these days. I don't think tips should be requested in any sort of transaction where the employee gets paid more than minimum wage. Restaurants always had this weird system where you could avoid paying your employees if they were tipped, so it was drilled into everyone's head "you're stealing from poor innocent workers if you don't tip 20%". But this is not the case for most…
Peak tip cynicism is when you're at an upscale restaurant where the wait staff are obviously being paid more than minimum wage, the bill automatically includes a gratuity (often 18% or more), and then on top of that, there's a line to include another tip.
If the restaurant is going to be shady and unilaterally introduce confusion to an already confusing norm, then I consider that norm voided and fair game for any interpretation.
