BUT, belle, it doesn't make ME selfish to think differently to you. IMO it is common courtesy to be patient and let the person in front of you finish in their own time - whatever they are doing. I certainly don't believe it is 'common courtesy' to move before you have finished what you are doing.
Would it be common courtesy for me to expect you to get off a loo while you were wiping because I believe you have taken too long to go and I want to go NOW? What's the difference?
I try to teach my dc to give everyone as much time as they need to get things done. Patience costs nothing and can mean everything is a phrase my dc hear a lot until they have learnt that.
If there was someone in front of you in, say, the post office queue that had 3 parcels to get weighed, would you be cross with them if all you wanted was a stamp? Would you be cross if they then made sure they put all their receipts in their purse as the items were sent recorded delivery? Would you get cross if they then decided they wanted to check their bank balance? Would you get cross if they then decided to take money out of their account? Would you get cross if they then decided to pay some rent on their rent card? Would you get cross if they then decided they needed to top up their electricity key? Would you get cross if they then decided they needed to top up their gas key? Would you get cross if they then decided they needed a phone top-up? Would you get cross if they put away their receipts in between each transaction? At what point if you were in the queue behind that person, and you only needed one stamp, would you get cross with them?
That is a list of the transactions I had to carry out in my busy local post office yesterday. Not one person huffed, tutted, or got cross with me, despite me being in the queue at 8.50, before the post office opened. Would you have? All my transactions were perfectly legitamate transactions, and I stowed the receipts in different folders in my handbag as that is how I keep track of my accounts - screwed up in my pockets would get lost, I have a folder for receipts from EACH type of transaction, so that I can keep track of my budgeting.
You'd HATE to be behind me in a queue...
