Did 6 Maccy Dees up till 2 years ago, they do not want to pay the price.
Started off at first, along time ago, at 7 days per week, then cut back to 5 then to 4 then ended up at 3.
Regular drive thru should be at least £20 per clean for in and out doing 3 cleans per week as it takes 1 hour to do a decent job, can be done in 40 mins if cleanish.
I was getting nowhere near this and in the end lost out to the gardener(not Alex, the actual gardener) who was paid a measly £8 for each of 3 restaurants and he made a really crap job. Asked me how to do it as it was taking him 2 hours each store I told him to feck off.
Ended up losing approx 10 grand of work in 1 month and I had cleaned their windows for 19 years, no loyalty there.
Cleaned ceilings, signs, drive thru lanes, frames even did a litter pick for them once as they were short of staff.
