This topic comes out periodically throughout Tower Unite, and I cannot agree with it more. A donation box, a tip jar, whatever you want to call it; it’s helpful to have for those that want to say thank you to the host and have zero use for units outside of gambling.
As implied by the above, I’d like to see something like a Tip Jar or Donation Box. This has been suggested before in both this thread and this other thread, and I think even just hard capping it to the current most expensive furniture item’s sell-price of 25,000 Units (from selling either the Shrine or the Snow Cabin) every 48 hours is good enough.
Touching on the subject of units being assigned a real-world value, this already something that is happening right now. While adding a tip jar would ultimately make it easier to do exactly what’s already being done (probably by adding client modifications to bypass any kind of tipping limit, I feel like it’s already something that’s happening as is and is too difficult to even keep track of unless you’re internally logging on some kind of console that states, “Hey this player received a tip of <x> Units from their Tip Jar!” Even more annoyingly, it’s harder to report current “black market” like behavior because of the anonymity of the people behind it.
Overall, though, I do think there’s more outweighing positives than negatives in terms of tipping players for their work in condos.
