Surely if you are a locksmith and Nigel Farage has locked himself out you want him to know you aren’t going to help him for a reason.
After obviously saying things like …..so you’re found yourself outside and it’s a bit shit do want to get back in …..
True.
My point is you could simply respond to enquiries "sorry, but we're too busy to take any additional orders / fix your door at the moment".
The rest is left to speculation.
