That is why you might have to make a local decision to change policy due to local constraints. If you only have three check in counters and hoardes of FFs, you might have one counter for 1st and Plats, one for J and Golds and one for Y and Silver. If you have 20 plats, 50 golds and 75 silvers you can't have them all clogging up the premium counters.
Likewise, you may have to rearrange boarding if you have a limited number of buses as some outstations do.
