watch out for expensive restaurants
one time i went to this restaurant and ordered some chicken thingy it cost five bucks and it was small, i was like yo i could go to wendys and get like 10 times this amount without a tip. to be efficient go to wendys and get a frosty, or if you want to be healthy go to HEB, its got produce
Unique Suggestions: only order water, then ask for free bread and chips, then see if you can flirt with someone, then maybe they will pay.
Fun Alternatives: if it comes down to it, make a run for it, usually the exits are labled, excuse yourself to go to the bathroom and dont come back
