Just that, really. I'll start with a few.
The way discount pop-ups scream at you on a shopping page as soon as you click on it. Excuse me, I haven't had a chance to look at the product yet, I don't KNOW if I want a 15% discount!!
Daytime TV adverts. Either they are for funeral plans, featuring perky older couples chatting gaily about "lovely send-offs" or overpriced tat that requires them to repeat the same information repeatedly for several minutes in the hope you'll be hypnotised into ordering it.
Supermarket layouts. Always moving stuff about, completely random grouping of items. For instance, my local Morrisons has just moved half its meat products on an aisle away from the butchery department.
I have dozens more, nothing major, but niggling.
