I wouldnt worry about it too much! As long as you do everything right, who cares!
I had a similar situation with an old neighbour.
They didnt like my car starting up at 6am to goto work (greenkeeper) however it was ok for them to have their son practicing being a DJ pill popper at 11pm on a sunday.
They got over it, Im sure this old bloke will to
And some old people can be real friendly, others just grumpy, got nothing else better to do
e.g. Xmas eve, mrs and I parked down a side street near Dan Murpheys to stock up on Xmas grog!
It was sooo busy! we got a trolley to bring a few cases back. Pack the car, mrs goes"I'll walk it back and meet me round the front" sweet as (Ive trained her well) and as she walks with troller, old bloke comes up
"you better not leave that there"
Just jumped at us. I was like wtf??? dont jump to conclusions mate, can you see what we are doing?
he then mumbled some crap. I said "excuse me, if you have something to say, say it so we can hear it"
his reply "dan murphys as parking around the back"
I kinda lost it - "have you seen how busy it is in therE? the main roads full, both parkings full, this is the only area"
as I say that more people are parking
rude barstard - asnd I was in a 323...imgaine what he would have said if I was in my 33!
