I remember doing a job in the Trump tower on Miami Beach. The building was new (at the time) and filling up quickly. Only one service elevator was in constant use and it could take 20-30 minutes waiting to get to the apartment we were assigned to work on.
Security getting in was slow and they insisted on keeping your identification as guarantee you would pass by when exiting to get you ID back. Since so many trades were working in the building, it wasn't monitored, especially if a trade was working on different units on several floors. The tile guys for example. One company could have several crews going back and forth to each apartment. Often they brought up large tool boxes on wheels. The same for carpenters.
I had resistance on one visit. It was normal to receive a stick-on badge that had my name, photo and the apartment number I was permitted to visit, now a guard was assigned to stay in the elevator checking my badge matched the floor going to. Everything going down was checked. I heard from a general contractor, someone got into a finished apartment (not under construction) and stole some expensive art work. This is what they had to do for being lax in the beginning.
Fast forward. In one development, it's standard practice whenever servicemen are scheduled to be in a homeowner's house, someone (owner, housekeeper, contractor's representative) must watch over the worker at all times. I support that plan 100%.
A few years ago, one of our workers 'strayed' from the area he was assigned to service and the owner caught him 'admiring' some of their art collection. It got back through channels that 'it won't happen again' and the serviceman was expected to be fired. Since he was actually a good worker, he was reassigned to only work on tract housing for developments under construction - before homeowners move in.
It's nice to know people invest in collectables. I had one client with a 'man cave' filled with sports memorabilia that had signed photos, baseballs, footballs, jerseys, shoes of many famous players.
What artwork I have are a few things inherited from my parents. Some faux- ivory scrimshaw and carvings. Not much of a collection.
My mother bought a 'Virgin Mary' plaque from a gift shop while on vacation in Italy.
My dad got something from a restaurant that was closing.
They were both satisfied with their art collection.
