Also on a terribly delightful note:
Customer: *sets down cup of trail mix that has craisins, raisins, nuts, etc in it*
Me: Will that be all?
Me: That’ll be 4.00
Customer: *starts fishing around in his wallet*
Me: *brightly* You know who also has really good nuts?
*everyone freezes – customer, and both coworkers*
Me: *slowly dawns on me what I just said, blushes and hangs head* Damn it.
(I was going to tell him that Trader Joes has an AWESOME trail mix and nut selection)
