Not a fan of it, but depending where you live (US and Canada tipping is a big thing) you typically got to go with the flow or else servers and friends think youre cheap.
My brother's example back in the 90s was the best. He gave $0 tip on the CC bill because he wanted to be a nice guy and leave cash tip in tray. When the server took the CC tray away to process, he came back and demanded a tip. My bro told him he was going to leave it in cash when he returned the tray. Based on the debacle, my bro told him him off and left $0.
That's the kind of entitlement you get.
I've worked as both a busboy and a server back in the early 90s and NEVER believe any server trying to tell you they are broke and make bad money. I worked at a normal family restaurant (not even a high end place or a super busy club) and when you factor in tips, you make a lot more money than people think. But every server will say their restaurant hourly wage is $1 less than standard min wage, so if a Walmart dude makes $10/hr, a server will say he or she is even broker because they make only $9/hr.
A server will try to convince the world nobody tips, every tipper is cheap tossing them $1.50, and all customers are grouchy assholes. Untrue. So pity them and tip big. The trend here in Canada is the CC terminals having default tip amounts of 20% and more. One place was 22%, 25%, 28%. I forget which place that was. The standard tip is 15%, but on those handheld terminals, they all start at minimum15% now, where it's usually options of 15, 18, 20, or 20, 22, 25. Something in that kind of range.
My best paying job during high school/university were those jobs. Even the busboy job I made around $12/hr after tips factored in. My server job I was pulling in probably $25/hr. And this was 30 years ago. Only problem with these jobs is you work dinner/evening hours killing your social life on weekends and if you dont do a double shift during lunch (I never did), you wont get 8 hrs worth of pay. My dinner shift hours were 5 to 10 pm. So 6 hours.
It's not a hard job either. It's actually easy. The "hardest" part isnt actually hard. It's just more of a fast paced hassle where it might be jammed and you got to run around getting food, drinks or the bill. It's not like you're building rockets here or even cooking food or mixing drinks. You're basically a messenger, not a builder.
I'd say the "hardest" part was setting up baby chairs because we had some sketchy ones which looked like they were going to break (they never did as they are probably sturdier than I think) and youre always thinking in the back of your mind if the baby chair will fall or break.
