Can I get a ticket for this?

I got food on my lunch & parked in a parking lot across the restaurant to check my food. I decided to hang out in my car for 5-10 minutes. I left the parking lot and noticed a sign that said it was reserved parking for only customers of this store. Can I get a ticket mailed to me or can they press charges? I never went in the store just parked in a parking spot for 5-10 minutes & then left.
