LOL. Your kinda right.
There are two onboard managers in LH - a CSM (red tie) and a CSS (chocolate-luv / mocha tie). The CSM is no1 and the CSS is no 2.
The theory is that they both form an equal part of the onboard management team - whether that actually happens on a particular sector is another thing tho (ie, depends on personalities!).
The CSS runs the main cabin (and is part of the Y/C service) and the CSM, whilst ultimately in charge of all cabin services, primarily runs the premium cabins (and is part of the service in J/C).
I guess its like being 2nd senior all the time
