No, your father is being right with the allowance. The issue is how plan to use RM500 to spend. Example eat simple food, no Starbucks, take public transportation instead of Grab taxi, etc.

Then if still not enough, you suppose to find a part time gig to earn some extra money. The whole process will make you stronger.

The hardest thing here is that people always compare why parents give me this much of allowance while my friend get that much. Never ending vicious cycle.
