I've only had one complaint
This makes me think the customer has over fertilized and/or over watered the lawn to the point where it has no root structure below the thatch area.
Drought drives roots deeper not more shallow.
Core aeration would help drive the roots deeper because it lets the nutrients & water go deeper into the soil.
Rent a core aerator and make a few bucks.
If a problem is occuring only at one customer's lawn I'd suspect it's their problem, not something you're doing.
