About 15 years ago, as a contractor, I did a field trip with the whole executive committee of a retail company, visiting several stores.

We entered/exited the store several times to check out the general store appearance.

After about ten exits/entrances, the clerks approached me to ask me to stop doing so as I was wrecking their purchase/visitor ratio.

If you pay attention in a mall, you'll see employees crounching to avoid triggering the sensors (they're usually at 1.5m height)
