I'm rich?

The Internet connection here is slow and I'm unable to upload any of my pictures so far. But I wanted to post before we leave this morning for our overnight trip to Mekong Delta.
Sunday was an interesting day... I braved the Ben Thanh market for some shopping (you have to bargain) and a $2 lunch, then went to see the Reunification Palace, but it was closed for lunch time. There was no where nearby to kill time. I was approached by some motorbike drives offering to take me to a few other places then back to the museum later on. I was scared to ride the bike itself, but the driver promised to go slow. He took to very interesting pagodas and Chinese temples, where devotees were chanting and the air was thick with incense. After the museum he took me back to the hotel, where we had a slight disagreement on the price. I thought I had established a price of 50,000 dong ($3.30) for the whole afternoon, which was in line with what my guide book recommended, but he tried to tell me it was 50,000 dong for each leg of the trip and he wanted something like $20. I was pretty pissed and tried to stand my ground at $5, but he gave me the guilty treatment about how I was a rich foreigner and had so much money for hotel, so surely I can give him more money. See, the local people see all foreigners as the same (doesn't matter if you are American or Australian or from Singapore) and that we have loads upon loads of disposable income to spend. I ended up giving him $10, but he was very ungrateful with that. To me he seemed greedy. But, I dunno, maybe other foreigners do give him same amount for similar services. He did wait outside for me while I visiting each place on our route. And he drove safely. But his attitude or the misunderstanding kind of tainted the experience for me and I was a bit upset afterwards, but I'm over it now. I was also very sunburnt on my shoulders, and I understand now why many women cover themselves completely and wear face masks while riding the motorbikes. You want to protect yourself from the sun and pollution.
My group is a good mix of 11 people. My roomate, an Aussie girl, and I are the same age and we are the youngest. There are some other single women, a bit older, and 2 couples. Our guide is a Vietnamese guy about my age. I think he's been with the company for 3 years.
Yesterday we had a short tour of the city by cyclo including a visit to the sobering War Remnants Museum. I also had some delicious pho (pronounced almost like "fur"). I spent the afternoon napping, as it was pouring down rain. I had dinner with my roomate (more delicious food for less than $3) and on the walk back to hotel I was accosted to buy a t-shirt. Actually the sales girl was really sweet and entertaining and I enjoyed talking to her. And, she was an effective sales girl. I ended up with a $2 t-shirt I had not planned on buying. And again, I was told I was rich. Hmmm, I never knew this before. I guess it's all relative. Anyway, I needed the extra t-shirt. I am sweating buckets here during the day.
Most of the people in Ho Chi Minh City seem to be working class - there is not too much poverty from what I can tell (but what do I know?). And many people seem to be in their 20s or low 30s. It's a young city. I think the Mekong Delta will be a bit different.
