Waitstaff Etiquette

I was a waitress for several years when I was younger. No one really taught me the ins and outs of being a great server. I just knew exactly how I wanted to be treated as a customer when I was out at a restaurant and I practiced the standards I upheld. Kiddies, I want to share with you my absolute biggest pet peeve where waitstaff etiquette is concerned.
It is the most presumptuous and rude thing ever when a waitstaff member comes to the table as you're paying the bill with cash for them to say, "Do you need change?"
NO. Attention waitstaff. You don't ever ask that of your customers! You put that ball in their court and say, "I'll be right back with your change.", letting them make the decision. Okay, I'm off my soapbox.
