Thinks it's perfectly acceptable for trampoline parks to charge an extra $3.50 for socks while requiring them - instead of just putting it in the base price.

Do you have to buy specialty socks? Or can you bring socks from home?
Yup, nope. You can re-wear the specialty socks on subsequent visits though - invalidating any claims that it is a health or cleanliness issue. I am including this in the strongly worded letter I write while my wife massages my shoulders, whispering encouragement, reminding me how principled my economic decisions are.
