They will need your signature on the check and your I.D. to use it. If the business is reliable, they WILL ask for ID. So nothing should happen. You could tell your bank to watch your checking account though. Alot of businesses don't take checks around here. My last job we had to have state code, manager signature, photo id, and license number on the check BEFORE we could accept it.
Sucks about the cash though. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
