I'll share another inappropriate things to say to a customer already on the edge true story. Working in a bathroom showroom back in the days when you had more choice of colours than just white;
Customer - I've got a problem with the bathroom suite I've had delivered
Phil (we'll call him Phil cos that's his name) - Ok, what seems to be the problem?
Customer - The toilet is white, as I ordered, but the basin and pedestal are cream.
Phil - Oh right, ok, I'm very sorry about that. I'll phone our warehouse and we'll get that sorted out ASAP for you.
Customer - But they've been fitted.
Phil - Pardon?
Customer - The plumber has fitted them!!
Phil - Why did your plumber fit them if they're different colours?
Customer - BECAUSE HE DIDN'T NOTICE!!!!!!
Phil, Wow, really? It's a good job he's not an electrician!
Pandemonium!!
