How Not To Annoy Your Waitress: A Guide
1.) When you need something, and your waitress holds up a finger to say 'one minute' DO NOT shove an empty teapot in her way as she's trying to get to another table. That other table has been waiting longer.
2.) When you order take out, especially a complete dinner (or two or three) during the busiest part of a Friday night, DO TIP. Because even though you are just picking up food, your waitress is gathering your meal and double and triple checking that you have the right items. This is time that she would otherwise be spending on the tables she already has. PLUS, she tips the kitchen based on a set percentage of money spent, which means that if you don't tip, the kitchen winds up getting the tips they earn on your ticket from from the gratuity of another table, meaning your waitress will end up making less in tips at the ends of the night. Seriously, even a few dollars will stop your waitress for thinking that you're a self-absorbed ass.
3.) DO NOT give your waitress a credit card that may or may not be working. Because she will spent an extra five minutes fiddling with the computer to make sure that, yes, your card is really and truly not going to be paying for your meal, which stresses her out and delays her from serving other customers.
