Does the accompanying person get the socks for free?

Für den Hüpfburgbereich bekommt die Begleitpersonen die Socken Gratis dazu,

Not in the trampoline area, since there are mats around the trampolines where the accompanying person can move with their own socks.

If the accompanying person wants to jump along (which is free and possible at any time), they have to buy the anti-slip socks for € 2.50.
