Thais call Bangkok "The City of Angels," but that doesn't include the tuk-tuk drivers and the scam artists around The Royal Palace who pop out like birds on a Bavarian cuckoo clock. Don't believe their cries that it's Lucky Buddha Day or that the palace is closed (it's open almost every day of the year) or that you can't enter without pants and long sleeves or that shopping is a better option. They're lying!
Markets pay these guys commissions by herding in tourists, we learned from Lonely Planet. Our book advised travelers to avoid chatting with eager conversationalists loitering around the palace and to forgo riding tuk-tuks in general.
If someone offers to stop at the Lucky Buddha or the "nearby" clothing store, find another ride--and thank those LP editors.
