Given how useless gil is in this game (500 gil? Thats not even covering ONE teleport fee), I think the much better reward you can give someone who you think has a cool glamour/mount/pet/emote/character in general is to hit /tell and give them a compliment (try not to be creepy, please... dont say anything to a female character you wouldnt say to a male, as rule of thumb).
Hearing "Hey, cool outfit!" or "Thats a really cute pet!" or "I really like the way your character looks" is probably a lot more worth than a pity amount of gil to be honest.
