My wife comes out with me some days. She great with the customers who like to yak yak yak yak yak because she does the yakking, which comes very natural to her, and I do the work. It speeds things things up no end.
She also keeps the van tidy because she says she not going anywhere sitting in a mobile rubbish tip.
The biggest drawback which sends me nuts is that it takes ages to get out the the flat in the morning. In fact, it takes her ages to do anything. I don't know what she does after she says she'll get ready but it takes her such a l------o------n------g t------i------m------e. I end up pacing up and down the front room muttering to myself.
Other drawbacks, she talks endlessly and we always seem to be going everywhere via public toilets. One cup of tea and 30 minutes later she needs the loo.
The bonus though, she's very thorough. We've got customers with front doors that are so clean you could eat your dinner off them.
