I think $20 is fine. And I have 2 sugars and milk in my coffee while I wait. Fair deal? Lucky I'm not Ken or I'd expect a selection of lamingtons aswell.

my useless input.

LOL, I dont have any lamingtons here so some of you guys might be out of luck! & I often do it while people wait, dont see the sense of making someone leave their car for the sake of 5-10 minutes.

Just inb case anyone wonders, I dont ever disconnect the battery, but I do unclamp it to give me that little extra room. I dont have particulalrly small hands but just seem to do it this way based on the time it would take.

& being a proffessional, I wont be sticking the glass up anyone's ass!-might be tempted to make you eat it though!
