Nope he’s a really nice guy, not a lazy bastard at all, and happily fitted our quite complex ducting including drawings so we could get someone to manufacture a duct for us to minimise corners due to layout and ringing the manufacturer for us.
he’s fitted lots of kitchens, his parents don’t have a fan I. Their kitchen they just open the windows, likewise for him. They all do lots of cooking, we know them….
he’s just seen a lot of people sold very expensive cooker hoods and ventilation systems that he’s not entirely sure they’ve all needed.
