Why did my husband roll his eyes at me over a small matter?

So me and my husband was going to the gym. We go on base to the military because I was in the military but this is a new base I've never been to. So I we were walking inside and he was all like "where's you card?". I said " it's in my purse" then he said with annoyed look on his face "why don't you have your card out?". I said " I'll get it out when we go inside... ". Then he rolled his eyes at me I'm like what. I caught that, it was basically over nothing not even a big deal.
