Asking The Horse After It Has Bolted

(I am at a wholesale store buying lunch for a working meeting. I go to pay and place down my items. When I turn back from putting the cart in the cart line there is a lady with two items between me and the customer before me, staring expectantly at me.)

Lady: “Can I go in front of you?”

Me: “I guess?”

(For the record, I would have let her go in front regardless. It was just strange she cut in line AND THEN asked.)
