First come first served? Not up to the driver

To be fair to Rowley here, he does have a point when he asks why some drivers think they get to decide who’s in next. Many a time i’ve “jumped” the queue because the goods in staff told me to. Ive also been waiting and had new arrivals go in before me. It might not seem fair but at the end of the day, its not the drivers decision so why they get all hepped up about it is weird. There could be any number of reasons its not first come, first served at that particular time.
Its annoying but its rarely the driver whos just arriveds fault you need to wait
