I think you’re on to something there. The maths just doesn’t make sense to me unless they’re in debt up to their eyeballs.I still think there’s something dodgy going on. Tax fraud or something.
My friend owns two restaurants, probably a similar size to Grim’s, and she thinks she maybe takes home about £35k a year at best after the running costs. I’d assume husband gets some sort of salary equivalent but I can’t imagine she’s paid anything? Three kids, her ‘renovations, her shopping habit, the weird holidays - it makes no sense.
