You really think a significant number of people are going to get on a plane to Switzerland and then drive to Vaud to steal pumpkins?

I there are always marginal effects, as an economist would put it.

It's also a society with really high wages, so the barrier to staffing a stand is higher.

San Francisco also has really high wages.

I don't see a lot of similar arrangements around here...

San Francisco has really high wages in a specific sector. How much does a retail job earn though?

In Switzerland, an entry level retail worker starts at around $4500 a month and goes up from there.
