Didn't have any problems - never have but I fly GVA/ZRH/FRA A LOT. I went through separate security downstairs where only one guy was which my bag was scanned and I walked through the metal detector, taken upstairs and there was the gate. Boarded.

Only hiccup (spilling red wine over my shirt) and it took passport kontrol about 2' to let me go after they scanned my passport).
