Did I Do This Right?

Last night this table asked for the bill and as I had some drinks to get for a 6 top I wanted to get this table paid and out of the way. He pulled out a gift and debit card.

I ran to get the portable debit machine and asked him if he ever used the gift card which was worth $50. He said no and I deducted that amount from the total.

I ran his card through and they took their copy and left before I closed the table on the Squirrel.

When I did , I noticed I over debited him $10. Well that was dumb on my part.

So I alerted all managers and left $10 in an envelope should they call back on the suggestion of a supervisor.

I think I covered all bases there. Alerted all managers and left $10 in the envelope in the office should they call back.

Now what happens this time if they email a letter to corporate this time??????
