We've had several threads about tipping at restaurants, but here's a new angle. I don't eat at cafeterias much, but it never occurred to me to leave a tip there. Now there's a big lawsuit by Luby's employees about sharing tip money.
you do have to tip at Sonic, but some places are getting out of hand like Mailboxes Etc where i went to mail a package b/c line at Post Office was too long. The lady gave me attitude cause I didn't put money in her tip jar for typing in a zip code to see how much shipping would cost.
