When there is a queue, please have your card ready. I don't need to see you go through your wallet twice, all your trouser pockets and your jacket pocket before you find it in a different pocket somewhere on your person.
If you get to the machine and there is a queue, please be as quick as you can. No need to check your card twice, your girlfriends card and then your card again. That notice isn't going to change. There is no money in your bank.
If there is a queue for only one machine when there are two, don't sigh, tut and walk over to the other machine and swear loudly when you realise it is out of order. We are not queuing for the fun of it.
Surely I am not unreasonable to expect this?? Any more rules I can add.
