So... a pretty disappointing experience. Upon arrival I was asked if my son and I had socks. I explained clearly that I had socks for my son, but I did not and that I would not be playing. The lady understood and approved this when she took my payment. Soon after, another parent had apparently complained that I was wearing sandals in the seating area. The proprietor acknowledged to me that she remembered my statement regarding socks, yet informed me I world have to either leave, or PURCHASE socks from her. She would not offer me a refund, but instead a coupon to return. Sadly, both the proprietor and my own stubbornness resulted in upsetting my son and our need to leave. But this could have been avoided by either requiring the purchase of socks BEFORE having pay for admittance, or offering free socks in recompense for the proprietor's error in allowing me to enter without socks.
