I've been mulling this over and I think Alex-Lydia has beaten me to it!
My thoughts were that you have, actually, gained from the day. You've gained a lot of valuable feedback:
- The marketing available on-site is limited
- There are, however, some treatments on your list which WILL appeal to this market.
- For some of your treatments you will need to market off-site. I don't know if, for example, any local businesses would let you do some mini-manicures, say, for free, one Friday afternoon during lunch and breaks?
Now, from this, how about ANOTHER day when you have a table with raw veg, fruit bites? Have a look at what drinks sell most in their cafe/bar, and put out small samples of these...hopefully the gym will sell them cost-price in return for you marketing them.
Have a chair, and offer 5-minute neck/shoulder massages, to people who have finished their work-out.
While you've got them pinned down (maybe not literally!) talk about how regular massage can help their performance. Get them to book a further treatment while they are there; we've all taken leaflets and meant, at the time to book in, but haven't followed up. It's better to get a sitting duck.
The next bit is a bit cynical, but play on their egos. Ask advice about exercise. Tell them, if it's true, how good they look. Establish a relationship.
I know you are good at this, but sometimes it's easier to see the problem from a distance, and I hope this helps. x
