Just a head's up on these if you pay using multiple gift cards:
I paid with four of them, and the values on three were completely depleted. When the server returned, she only included a receipt to sign for the card with an amount remaining on it [which I used for the tip, along with .97 cash]. The editor didn't care for my explanation and left a note that it wouldn't be approved next time.
"Gee, can I have the receipts for those gift cards that aren't worth anything now? My husband uses them to floss his teeth."
Lesson learned.
If your path dictates you walk through hell, do it as though you own the place. -unknown
