Globe seems fairly priced to me
The average net take home monthly salary in Zurich is CHF 7,841. If I visit Globe and pay CHF 105+140 for 1 session, and I go every week (52 weeks) for a year (12 months) that works out at 13.5% of my net take home pay. The average net take home monthly salary in Frankfurt is EUR 4,050. If I visit an FKK club and pay EUR 70+50 for 1 session, and I go every week (52 weeks) for a year (12 months) that works out at 12.8% of my net take home pay. So, as a local living in the Zurich area, I find no real arbitrage opportunity in the pricing between German and Swiss clubs. Obviously as a foreign visitor you get "more bang" for your buck in Germany.
