On holiday.
Are all you trade sellers trained to be like this to DIY bods, I went to our local plumb trade place for a central heating timer a few weeks back. Showed him the old one and asked if they had something that would fit.
"Ah yes you want one with hotwater and central heating on it"
I could see that myself given that's what was written on it but I was polite.
"Yes, that's right thanks"
"Well we only have one like that, this one."
"Do you mind if I check the fittings as my system is old….err it's the wrong fittings"
"Yes some do vary, that'll be £65 please."
"Why, it won't fit do you have a plate for it so can I rewire it?"
"No, but I can get one for next week so that's £65"
"What I'm not buying it, there's no point if you don't have the fittings"
"Errr!"
So back to screwfix for me, that said the local builders merchants I use or very good indeed most helpful well stocked and cheap.
