I think it becomes slightly less offensive when it's ancient and the product/service doesn't really exist anymore - it feels like you're walking through a museum instead of looking at an actual advertisement or something, at least to me

I worked in the Electronics/Sporting Goods (sometimes both when understaffed) and Gardening departments of the local small town K-Mart when I was in high school.

Can't say I was overly fond of the throwback 80s music it played or the cheesy product ads after hearing the same ones for weeks on end. This was 15+ years after the 80s as well. Thanks to this discussion, I unfortunately have them stuck in my head once again after years of suppressing them :(

It was actually a pretty decent job for where I lived and for being in high school (with above average high school pay). However, I never ever liked the radio system or the pre-recorded announcer.
