My first year I had my first EOW. The customer lied and claimed her lawn never grows. The lawn needed to be cut every week. We parted ways half way through the season.
Second year I was asked to do a lawn weekly and her FIL's lawn EOW by a new customer.
I relayed my bad experience from the year before and that if the lawn grew too much it was going to be switched over. She said FIL's lawn hardly grows. She was truthful.
What I have decided to do when someone wants EOW I will tell them that the lawn gets mowed once. There will be no 2nd cuts done to make the lawn look good.
I also now price my EOW lawns 50% more to the extra load the taller grass puts on the equipment. The customer still saves money.
$30 cut @ 4/5 month $120-150.
$45 cut @ 2/3 month $ 90-135.
