Made a cashier leak

So I walked into a store that was pretty busy when I pulled in the parking lot I guess the girl had just got a moment to herself and was rushing back to the bathroom when I walked in she heard the bell on the door and had to come back to the register as I was gathering my stuff she was pacing back-and-forth behind the counter. As she was ringing me up she was dipping up and down behind the counter and I heard her whimper and mom and say oh God not now. As I was leaving she was shuffling her way to the bathroom with her hands between her legs
