I filled this in relative to my last job, and then realised I shouldn't have answered question 1 ... sorry. Anyway, none of my jobs have involved bonuses; one did include a proportion of profit-related pay, but I can't remember, if I ever knew, how this was calculated.

I suppose one could argue that M's wedding and funeral fees count as bonuses, as they are additional to his regular stipend, and ministers will get different amounts depending on how pretty their church is, how willing they are to marry divorcees and/or conduct blessings of civil partnerships, how good a relationship they have with the local undertakers, etc.
