Last leg of backpacking adventure in Vietnam.

2 Approaches in Saigon

Approach 1
See homely blonde girl walking towards me, I stop her and ask where the war museum is. It goes well, she's english we chat for about 10 mins, she's leaving in a couple of hours for Cambodia but seems to want the interaction to continue.
I get her number and say bye, I really wish I would've instant dated her for coffee grrr

Approach 2
I'm having lunch on terrace restaurant, 2 aussie girls sit at the table next to me. I leave it a few mins then ask if they've been to the presidential palace as I'm thinking of going there in a bit. They havnt but offer other good advice, we chat for a bit then back to food.
After a few mins one goes to loo and the other reopens me saying do you have to order at bar. We chat for a lot more including when other girl back, end up swapping numbers and saying we should party one night, they agree.
