I did break my "regular only" rule yesterday.
Pleasant mannered attractive lady (always helps) next door to one of my regulars asks if I can just do her front two windows (one up, one down) including the plastic surrounds please.
"Are you looking for a regular cleaner or just a one-off job" I ask.
"Just this once for Xmas, but I might ask again if that's ok" she says.
"If it's not regular then my rate is much higher, it'd be a tenner."
"That's fine" she says.
So pole and hose were out anyway, took me ten minutes extra (did a thorough job), she's happy, I'm happy.
The exception that proves the rule!
