That first bloke, sorry but there is someone who will want their windows done regularly but will want to chat and chat and talk and talk.....
Interesting character he may be but....
I've quite a few customers like that and I really should dump them but I still clean their windows and I listen to them talking away while hoping from foot to foot thinking about about how I really need to be getting along and working.
As for the wasps, try cleaning that window in about a few weeks when they are all starting to get a dip dopey and drunk on rotting fruit and the queen has left the nest and wasp social order is breaking down.
