Input: Text: so i work at target and today was a pretty rough day for me.
after helping a guest (we're not ~*allowed*~ to call them customers) find something and being thanked, i tried to tell them "you're welcome" and "no problem" at the same time, but i instead said "your problem" with a right smile on my face.
after noticing the mistake, i quickly shuffled away down an aisle in hopes they were so cripplingly elderly they didn't catch it.
