This is a byproduct of low price marketing
Your prospective customer might have been exposed to this sort of presentation in the past:
The guy shows up for 9.95 a room or some other ridiculous price, then upcharges for stains.
We had an apartment cleaner around here who did a one bedroom apartment for 35.00. But he charged 100.00 extra if there were stains, and 100.00 extra for pet odors.
Of course, every job had both, and the managers fell for it.
One finally didn't, so when stuck with a 35.00 job, he sprayed the carpet with water, raked it in, and sent them the bill.
He had a big business going until his business ethics and personal behaviors conspired to catch up with him.
Recently I Subbed for an aquaintance. Was sent to an apt. community for some color repair work.
Something the regular carpet guys do not do.
I do know the maint. supervisor, have for years.
A higher end community. He told me his regular guys charge 55.oo for their two bedroom gardens.
These are rather spacious . Living room dining room combos, but large. Oh , and the two Brs are upper level , with carpeted staircases to access.
If rotaried 65.00!!! Yeah right.
And , he told me if any extras rarely more than 10.00. reds etc.
Yeah right.
BUT , you make it up in VOLUME!!!!
I tell these people, I were offering $1.00 bills at .50 cents I could most likely have a never ending supply of customers. !!!?LOL
This outfit had 5 or six trucks going serving that market, I am told.
