people who are saying $50/$100 is wild. $20 is ok. $10 is ok. in malay we call it ‘ikhlas’. meaning sincere. as long as you ikhlas, its considered alot alrdy. also, you’re NOT OBLIGED to :)
The amount depends on what you are able to afford. Ill say $50 is a good amount. Some give $100 too. Really up to you. Its more of the thought and sincerity then the amount.
