Sims don't stack spoiled Drinks from Drink Trays

I have this issue also and it's very frustrating and spoils the fun of serving tea to others. The only way it does not drive me nuts is if I have a butler right there cleaning up each tea cup on the tray individually, though I don't always see them getting this job done efficiently either. I also found clicking each individual tea cup (that has spoiled on the tray) to request it be cleaned up rather fiddly and very annoying. It just becomes a high maintenance mess. So disappointing.

What I expect to see:

• Like with coffee, if a cup was taken from the tray and left out, it should need to be cleaned up, but it can be stacked on other dirty dishes if needed. 
• If the pot of tea and the remaining cups on the tray go bad/spoil, they show fumes and an option to clear the tray and have it done and ready for re-use.
• Alternatively, if you felt it needed a clean up action, have a 'clean up/clear tray' option on the tray that results in the sim carrying a stack of dirty dishes that can be stacked and taken to clean. (And this leaves behind the clean/reset tray.)
• Wish list: It would be a nice detail if there was a note on hover that told you how long until they spoil. Also, it would be great if we had an option to just clear the tray/reset it before they spoil.
