Vantaggi
Flexible hours, free membership, short shifts if you're part-time. Good gig for students. Not something you should do long term though
Svantaggi
They are always looking for a way to cut costs, meaning a way to fire you. Absolutely must treat it like nothing but a job because they do not care about you, the extra work you do, or your personal life. Especially if they can find someone to replace you with someone they're friends with or who will take cheaper pay. Do exactly what is asked, when if is asked, even if it seems like other employees get away with doing less than the minimum because they will fire you with no notice and let you find out on your own. Then they won't admit that they did it and they'll lie about it. Very poor culture here.
