Even more adverts you despise

Why do adverts insist that people eat at their desk. Aldi with yer woman having a bowl of cereal at her desk and various other assorted Shiite food sitting on the desk too. The McDonald's advert with the oriental girl sitting at her desk spilling the dressing from a burger onto her lap and then wiping it with her finger and licking it.

Any office I ever worked in, if you did that at your desk you'd be getting a written warning from HR to get da fook down to the kitchen/canteen for your eating, ya durty Clint. Can you imagine the smell in the office if someone brought in a McDonald's, or the state of the desks/floor if everybody had their breakfast al desko.

Don't even start on the ludicrous Andrex toilet roll advert where the lady let's off a massive fart and this is her cue to meekly head off to the Jack's and the other staff knowingly approve because she has a roll of Andrex and a (possibly communal) book under her arm.

Is this office culture in some other part of the world, that I've never been to? If any of the women (or even roughest lads) in my office did that there would be hysterical laughter followed by about a year of acidic slagging from the staff and crippling shame for the culprit
