LH agent(s) in UA Clubs?

Hi all,

I have read that Lufthansa agents are available in United Clubs at outstations for several hours before a flight. Does anyone know if this is true at SFO? In either the int'l first lounge or the UC?

Reason I'm asking is I'm connecting from LAX on UA to SFO-MUC in LH F and have concerns about presenting a UA F boarding pass to the F lounge agents in MUC, even though it will say the flight was LH in F.

Thanks!
