Input: Text: i work in construction and have been working some serious overtime the last week. i'm not accustomed to coming home at 830/9 on a friday night. now, i should preface i live in chicago and we have "tamale guys". these are mexican gentleman that carry igloo coolers into bars and call out, "tamales" selling them to drunk patrons in prepackaged delicousness. on my way home this past friday, starving and looking forward to going home and relaxing, i encountered one of these gentleman near a bar as i walking home from the train. well, i should say i thought he was one. as i came upon him i heartily exclaimed, "i'll take one!". i received a very confused look and a "i'm sorry, what?" in a very americanized accent. "are you selling tamales?" as i pointed to his igloo cooler. "uh, no. wha-this is my lunch box." my cheeks instantly turned hot as i realized i just assumed this guy with a lunch pail, not unlike myself, was selling tamales because he looked mexican. "omigod! i'm so sorry!" i was mortified. he realizes and starts laughing. "oh, wow! it's cool, man." we had a little laugh and walked our separate ways.  i can't tell you how greatful i was that he wasn't offended. i felt like a huge idiot.

TIFU by being kinda racist.
