Yeah I have a bit of retail, 10 shops, a pub and a restaurant all closed up for now.
I also clean an office block in one month, out the next so I've cancelled the internal clean due next week, so I'm about 500 quid down.
It's ok I've got plenty of work and have always lived within my money.
I stopped relying on retail some years ago when I lost over £1000 of work a month when they changed cleaners. I have a more varied customer list now, it spreads the risk.
