For those who do gas station routes, call your credit card company and let them know that you will be using your card at different gas stations on certain days.
I did a four station route for two MSCs last month. Let my credit card company know that I would be making 2 purchases at 4 different yellow gas stations on Monday (which was a holiday). They noted my account. In one of the reports, the MSC wants to know if the same card had been used at multiple stations. I let them know that my credit card company was notified.
