Trash Cans?

Will someone be emptying them as they get full or will they just be sitting until the end of the night? If someone is watching them then I don’t think you need 10 but if no one is going to empty them until you clean up at the end of the night then you will probably want more than less. I think 6 would be good, one can for every 20 people plus one extra. I think placement of the cans is probably important too so people are not all just using one can.

I definitely don’t think you need 10 either. I think 4 might even be enough but 6 would be better just so that the trash isn’t being piled into one or two only
