What would the world be like if there were no table service?

The first thing to do would be to line up with a clean plate in tow. Then pick out colors and shapes, and someone will slop it on your plate.
While balancing your plates, you will have to find an open table and pop a squat.
Oh is the Salisbury Steak too rare? Normally this kind of situation would be an obsequious servers fault. Instead you would have go back to stand in line and translate your issue to the Mexican cook.
You forgot to get a straw? You can’t ask a nice smiley waitress for a straw, instead you have to walk all the way up to a counter and ask someone else for a straw.
Oh you need a refill now? Can’t find anyone to get you a refill? Can’t see a refill station? Then get your ass up and find the nearest bathroom to refill your cup with luke warm water.
Oh you finished your grub? Now you have to go put your dirty plates in a smelly buss tub.
Ready for dessert? Go to the back of the line and grab another clean plate. It’s a hard decision picking out a colored triangle for dessert. You think that’s blueberry? No. Wait. That one is moldy rubarb. Ooh apple pie. Your mistake, that’s a rotten pear in a napkin.

Gee somebody who will get you just what you want sure is nice.
