My first job was up at Taco Bueno in Denton. My friends would fill up the ash trays with hot sauce. The, they would smash a burrito on-end on the table cuz they knew I had to clean it up. $3.35 an hour.
It amazes me how dumb people can be, working in the service industry.
I drive to the airport, in the shuttle, and people will come up to me "Are you La Quinta" and very nicely say "No", but under my breath, "Can't you read, you idiot".
