As a former waiter who spent over a decade in the industry, working everything from casual to high dining, this comment irks me at a personal level. These examples are not directed at you but an explanation of how a waiter sees the situation.

1. Some Point of Sale systems have a limit on how to split a check. I physically cannot split a check more then 6 ways and the customer is asking or 7 ways, then what am I suppose to do? Be "nice" and promise the impossible? So now I pissed off a customer who's about to tip me because I cannot reprogram the POS.

2. The more likely scenario is when a table of 7, who just had pre-fix brunch is asking me to split a $70 check 7 ways which takes my time away from my couple who just dropped $70 by themselves.

What customers in restaurants don't understand is that tipping might be optional but my time is money. As a customer is tipping on service, I'm also providing service comparable to the tip I receive.

Waiters are really good at "guessing" how much a customer will tip and will act on that belief.

Disclaimer: I worked with a ton of awful waiters who were straight up rude to good guests. No guest should ever be treated poorly.

Ive also served some awful customers:

Some of them tipped very, very well because they wanted to be awful. I loved those assholes and always welcomed them with open arms - money's green regardless.

Some were just awful and I tried to steer clear of them.

Now as an olive branch; all guests should be treated with outmost respect and all people in the service industry should be as well
