Buying local food from train vendors on the way to Kandy

The train vendors are heavily regulated by the railway authority and are not scammers. They provide a vital and safe service. The hot snacks like roasted peanuts, wade (lentil fritters), and sweet tea are delicious and safe to eat. They might occasionally round up the price from 80 LKR to 100 LKR for a foreigner, but it is not a malicious scam.
