What sales technique do you hate to have used on you?

i hate it when they use scary stories to make people buy something. One time soemone wanted me to buy a gas regulator and she showed me all these fire and bombing breaking out on some house because of lack of regulators. Its not nice:P

I hate call-centres ringing me. I find it really annoying, as there is no way to get off the line quickly without being rude. There is also a scam now where it can cost you to stay on the phone with them, even when they call you. I also hate pop-ups. They always appear at the most inconvenient time!

i hate it when they go very persistent which may lead to annoying. i hate it when they kept going on and on about how good their products are and how it will benefit me when in fact, they dont even bother finding out what is my need beforehand!

I just hate every technique that they use on me. They always just try their best to get you to buy their product even if you don't need it.

I hate persistent efforts by sales personnels to just make e take another look and refusing to listen to my pleas that I really do not need their products. I hate dodo rp door selling too. Its genrally in the afternoons when they knock on your door and insist to show you their products. You want to be rude to them then feel bad about it too.
