Wow, that is brutal. I would hate to be ‘that’ employee.
I agree, in any form of customer service, I expect a certain level of professionality. If you go above and beyond, then you should receive some sort of positive reinforcement. If you are subpar or worse, usually a toxic demeanor, then in one way or another, you should get your comeuppance.
This is how I view waiters or waitresses and it’s pretty much along the lines of the 5 star system.
I start off neutral, 3 stars. If the waiter or waitress goes with the motions and does the minimum, staying 3 stars, then I tip the minimum which is usually 2 times the tax. I figure that part is usually added to their hourly wage. So, the person earned their hourly wage, whatever that is. Hopefully the person isn’t shocked when he or she realizes that his or her tips are meager compared to the other waiters and waitresses.
If the waiter or waitress is a 0-2 stars, then I tip accordingly. 2 stars = the tax, 1 star = half of the tax, and 0 stars gets 0% of the tax. Yes, I have left $0.00 as a tip before, due to a rotten waiter or waitress. Usually, when I do that, I don’t plan on going back. I don’t feel any amount of regret either, even when people qq and say that they need those tips to make a living. Well, when you are heavily dependent on tips, be a better waiter or waitress, or get a different job.
If the waiter or waitress is a 4 or 5 stars, then I usually go for 2.5 x the tax for the 4 star and 3 x the tax for the 5 star. Sometimes I round up to the nearest whole dollar. I’ve even dropped a 50% tip before because the waiter or waitress was really nice, professional, and attentive. Those people definitely make me want to revisit that establishment again. I like getting their names too, so I can request a table in their area.
