Examples? Let me flip the question around.

Consider this challenge: if I were to magically plunk you down in any thrift shop on Earth, with no-one around, the windows and your smartphone blacked out, how long would it take you to find suggestive clues regarding:

- what continent and nation
- rough latitude
- local climate
- proximity to ocean
- languages commonly spoken/written
- general condition of the local economy
- trading partners
- ethnic mix
- leisure activities, sports, hobbies, entertainment
- prominent local employers
- what kinds of foods people eat in this area
- how do they cook
- mix of local politics
- mix of education levels
- high or low crime/violence rate
- predominance of young families or retirees

And that's just a few coarse indicators, off the top of my head. The unsorted donations in the back will tell you even more.

If hikermor's archaeological successors, 10,000 years from now, found a thrift shop encased in amber (or peat or volcanic ash), they'd be over the moon.
