I got a call this morning from a building firm I work with about a customer with no HW or CH.
As it was Sunday morning and I live local to the job (everyone else is at least 20 miles away) the owner of the firm called me and asked if I would nip round for a quick look.
I went round and fixed the fixed the problem. However I was looking after my girlfriend's 5 year old lad at the time so I took him with me.
The ungrateful bastards later phoned the company back to tell them I was unprofessional by taking a child to work with me. That phone call moved them from a "free courtesy call out" to a "billed call out" as they could have fixed the problem themselves. With a bit of luck they will get the bill on Tuesday morning:-)
