This has probably been discussed before but times change and so do habits so I'm putting it out there again.
I'm just wondering if the Vietnamese tip when going to a coffee shop. I have some Vietnamese friends that do if the service is good.
Also wondering about the tipping habits of expats ? do you tip ?
I usually leave about 4000 dong for the staff if I just order a coffee in a cafe. Leaving too much of a tip though or at an inappropriate place (like a street stall) and you look like an idiot plus make those around you feel uncomfortable.
