Luckily army has prepared me for this kind of situation. Celebrity restaurant is no walk in the park like the other normal restaurants i've worked in. Its not the hours or people, but the want to excel beyond what i am right now that keeps me on overdrive.
Sometimes, after a day of hard work (no time for lunch), the EC said some words of encouragement (e.g, "you are doing good" / "its because of your prep since early in the morning that smooth service is possible" / or simply just a "thank you for today" ). That is the satisfaction!
