In Phnom Penh street side stalls quickly appear from no where to cater for the "must have" of the day/week/month etc.
For example, when the police started to fine people for not wearing helmets many stall owners started to sell helmets and made a tidy profit as (nearly) everyone rushed to buy one. Some might think Valentine's day is a day of romance etc but here it seems to be the day to make a quick buck. On most streets there is a rose seller or two (...or ten) encouraging young Khmers to buy one for their sweethearts.
A large Khmer nightclub, called Rock, is also having a Valentine's special. You can take your date to the "night" club between 1pm and 6pm this afternoon and get two free soft drinks!!
