I made a list before we left. Got inside the store, some heavily perfumed lady almost rammed me into the service desk, then a woman who reeks like a wet ashtray mixed with wet dog ran over my foot with her cart. I handed the list to DH, and said "you are on your own. I will meet you at the car" and I left. I sat in the car till he came dragging out 30 mins later. I said "see! this is why I hate the store!" He said it got much worse after I left, and he was glad to see that I had gone to the safety of the car.
Perhaps next time he can go completely without me.
