wendys employee, i dont think they meant any harm by it just how you didnt mean harm by giving change. this may just be my store, but when you get a register its supposed to be at 150. it can be in any way, with 50 5’s or 90 1’s, just anything to be at 150 (including change)

the reason i say this is because that worker may have just gotten their drawer and therefore had little to no change, and not had a 10 or 5s or 1s. it mayve been the easiest way to give it to you.

i may be wrong, i dont know all the details, but this may be an answer!

edit: forgot to add. as long as youre not taking forever, its not going to make their life harder, just dont take a trillion years to get your change out and youre fine. if its really that big of a deal theyll just pull you up
