We're talking past each other it would seem this was my first comment on the thread which appears you missed:
Simply put we don't disagree at all about the fee. You stated it should be on the purchase of shoes, I didn't disagree (I never negated that in my comments).
Repeatedly I said I disagreed about just trying on shoes and a fee charged, which is the application this store is using. It would appear the whole time you've argued against something I didn't even say lol
So to repeat for the nth time (because I'm not quoting the multiple comments where I explicitly said what my problem was with it which was putting a foot in a shoe period=a fee), my issue was about a fee assessed the way the OP described it "Yes, if he tries on any shoes and doesn't buy, he would pay the fee."
I suspect that's a turn off to many customers who don't want to incur a fee for putting their foot in a shoe even if they had every intention to purchase, how many times do we go out shopping but don't find what we're looking for, or a shoe doesn't fit, or a million other reasons outside of always intending to shop online. FWIW I'm not even sure legally (ETA: well more practically) speaking how a store applies this fee should someone actually take them seriously as in how are they prepared to collect the fee charged to a non-paying customer.
Pretty sure we've said enough to each other but suffice to say again we never disagreed about the actual fee being charged
