Our company doesn't employ any co-pilots although we are required to operate 2 pilots up whenever pax are flown. We are all qualified single pilot IFR in the aircraft we operate. We both wear 4 gold bars although we aren't an airline.
It doesn't really matter much, IMHO although I might just sneer a bit at the R-22 PPLs wearing similar.
I don't get to pick any girls up as I am married and old. Shame. They all try to pick me up though. (ROFLMAO
!)
