You have a choice to make; you can conclude that lots of people are just taking a poke at scousers or you can ponder if there might be something it it.
For my part, I used to deal with a number of pie delivery men who worked all over the North West. They were quite relaxed when delivering to chip shops in all areas except Liverpool.

I leave it to your imagination how they did that.

All of us old football fans have memories of eight year old kiddies looking after our cars for a fiver. It might have happened in a few other cities but never more than Liverpool.
After all the comments above I doubt if you will be able to relax if you do decide to park up near the docks.
I think you will find that the replies, inc mine, were said in Jest. All East Anglians are slow, all Yorkshiremen are know alls, all Scotsman are tight, come on lighten up a bit.What a incredibly insulting post to the people of Liverpool
