Modern mics that clip to a shirt means they can pretty much whisper their review. Doing it inside lets them show how the dining experience is such as the atmosphere of the restaurant, what kind of decorations they have on the walls, how the food looks properly plated instead of crammed into a take out box.
Someone politely and quietly doing a food review doesn’t impact your dining experience much compared to anyone else dining at that table.
I agree for most things, they were just built to last a lot longer because product quality was a priority. These days, a company doesn’t want you to buy once, they want to sell you a product that lasts just long enough you’ll buy the same brand after it breaks. I’m a tradesmen and I can attest, the older a tool is, usually the higher quality it is. Same goes for lots of equipment. I once saw a sears model pressure tank from 1972 still in working condition when newer tanks last 5-10 years and the average before that was 15-20. That specific case might be survivorship bias, but every retiree i talk to will claim sears had some high quality stuff when they were yoinger.
