This was suspicious? It was from a small Mexican restaurant, what did they expect?
Several years ago my car loan was paid off. It was an automatic deduction from a credit union and the deposit was an automatic deduction from my pay. I closed the account and took the balance of the savings account in cash, about 22 $100 bills. I started thinking of the forfeiture actions on the way home. I drove very carefully, not wanting to be stopped and searched. $2200 was more than the average person would carry.
If you have the receipt on your person from the local bank, I wouldn't think it would be an issue. You were probably more at risk at being robbed.
