I find it best not to laugh like a hyena when they accept a quote - it really is offputting.
running away and screaming "WOOOHOOO!!" doesn't do you any favours either.
That made me smile.
However, I phoned a £40 customer this evening; I do her every-other-month; it's a bed and breakfast place, not big, takes Wor Lass and I about 30 minutes to clean it, and it's out in the sticks.
She said, "How much is it again?"
Me, "Forty pounds; same as last time".
Her, "That's a hell'uv a lot of money!"
Me, "SJ, you've got a hell'uv a lot of glass!" (But it's stacked close to together, a big conservatory (easy with the WFP)).
Her, "Well it never cost anything like that before; [sigh]; okay never mind, see you Tuesday".
I suspect her last window cleaner underpriced and never returned, but I sense that I'm not giving her the warm fuzzy feeling I'd like to (no sexual innuendo intended).
