I need to go for a specific type of facial that requires the practitioner to work in detail on different areas. When I first found my current practitioner, about three years ago, I was delighted with her as she did an incredibly thorough job. About a year ago, I started suspecting that she might be putting less effort in (leaving me under steam/mask/lights longer and spending less time doing the "work"), but after the last two times I've become absolutely certain that this is the case.
I had the same experience with a manicurist; brilliantly detailed work to begin with but then she started getting less attentive when I became a regular customer.
They haven't lowered their prices (in fact, they've increased them, which is fine by me - I know there's a CoL crisis) nor do I get any perks from being a long-term client. I also always tip around 15%. So the only reason I can think they're starting to slack is complacency.
Of course, I know it's not everyone - I've had the same hair stylist for 15 years and he never falls short - but I'm wondering if this is a "thing" in the beauty industry? And how does one make sure a high standard is maintained without going into nagging/difficult customer territory?
