I would have stayed where I was if I was next to be served, often when they open a new till you unload your trolley & Cashier is still "faffing around". I will not tolerate any-one pushing in though & would loudly say "excuse me but the queue starts some-where behind me" - usually works as everybody looks at them !! 
The one thing that used to annoy me though was when I was working I often went into M & S Foodhall at Lunchtime, very often when I was queuing a "little old lady" (not the same one every time!) would say "excuse me but can I go in front of you I've only got one item?" I used to politely refuse stating I was on my Lunch Break & would be late back to work !!! 
Now I'm retired I try to avoid Lunch time shopping after all I've got all day
