Frankly speaking, Cambodia, as a developing country, is not a very ideal destination for travel alone. Thailand and Vietnam are both better choices.
For example, Sihanoukville is Cambodia's third-largest city and the largest port; from a certain perspective, it should be the most prosperous place in the country, but the situation doesn't look great now.
Although Leonard knew before coming that this country is small and backward, with poor infrastructure, he really didn't expect it to be only on par with a Chinese county town.
Also, Cambodia, like the United States, is a tipping country; small tips, however, of about 1,000 riels (equivalent to 1.5 RMB) are acceptable.
If tips are just uncomfortable, the big security issues of motorcycle thefts and robberies here are a real concern. It must be said that although casinos can indeed boost the local economy, the downside is the sharp decline in local security.
