I'm with MDavis... I'd contact the MSC because I think you're right ~ that would look way too odd.
I live in an area that rarely gets snow, and when we got half a foot it was substantial for what we're used to. I had a shop at a grocery warehouse type place. I contacted the scheduler and told her that while I had someone who could drive me in the snow, it would look *really* odd for someone to go to a place like that (where you don't just get the quick milk and eggs type stuff) and then just get the $20 worth of stuff they reimburse, with the weather situation. Especially since they're a smaller place, with only three checkstands and each customer gets noticed. She agreed and rescheduled me.
