Hey guys!

I think I've seen a thread like this before here but couldn't find it anymore. Just made this out of curiosity.

Anyway, as the topic says, how much do you tip the ff. people?

1. Waiters from restaurants
2. Gas station attendants (for air, windshield cleaning, etc.)
3. Parking boys
4. Mechanics
5. Barbers / hair stylists
6. Car wash boys

Please do add more if I missed out on some others.

Thanks!
