I wonder if you feel the same way with someone who queues for McDonalds and orders a BigMac, then changes their mind and orders a Chicken Sandwich, do you feel they should go to the back of the queue or be allowed to change their order whilst maintaining their queue position?
If it was separate queues for each item then yes, if a single queue to front and then choose ok, but these dweebs chose a certain card now want to jump into another queue at the same position.
If you did that in queues at Post Office counters etc you would get thrown out.
