Well yes, that's a lot easier than trying to do it at the recycling facility. Do you expect the garbage man to do your dishes? The easiest time to rinse off the container is immediately after it is opened. By the time the container gets to a recycler the residue will be caked on. You use plastic bags to protect yourself but you aren't thinking of anyone else.

Why would the garbage man do my dishes?
Look, I throw away my trash because it's super convenient and the city provides a wonderfully helpful service of hauling my garbage off for me. But if the city comes to me and says "Hey, we want you to come out here and help us dig the landfill, because it's actually easier if you do it" -- then I'd probably just light my garbage on fire or toss it in a river.
