If Service is so "excellent" why is retaliation against not tipping just not doing your job?
If what you're doing is so above and beyond your job description, why is it that when I don't tip, you won't even do that? Instead, you actively go out of your way to not take my order, and intentionally do not pick up my food for hours on end.
instead of cutting out the actual part of your job, why can't you cut out whatever is making your service "excellent" (and I'm not entirely sure what that even is).
