People (usually cabbies) sitting in their cars outside beeping their horns.

Just get out the car and knock on the door you lazy basts, instead of disturbing everyone else.

You can turn the bass on that stereo down as well while you're at it; arseholes!

No need for the bass, drives me up the wall. And beeping your horn is rude. But I would say if you know someone is coming to pick you up its polite to look out your them.

I used to pick up a friend at the same time every week to go to a group together. She never once peeked out the window and always waited for me to get out and ring the bell. I actually thought that was a bit rude.

I don't mind a horn in the day, but the nighttime beeps are not acceptable.

"I don't mind a horn in the day"

Horn blowers are twats. Our taxi texts us.

[Andrewofgg]

Text, phone, doorbell - using the horn is just idle and anti-social.

Taxis here ring your phone, but I can't get upset about a quick beep!!

[CaptainHammer]

YANBU. It's never just a little beep round here either, always a couple of proper honks that sound like they've punched the horn with full force!

sharesinpampers That would wind me up too. If someone is picking me up I'm ready and waiting by the door about 10 minutes before they are due!
