1. Restaurants in less or more touristy areas prepare Westernised Thai food when they see a tourist. The only spicy food in touristy areas I had was after I clearly stated that I want traditional Thai style rather than the tourist abroad way. In all other cases I had Thai green chicken, which was more like a korma.
I actually believe that I only had real Thai food once, and that was in Bangkok when I kind of get lost and ended up in a working part of town where I could only see Thai people. Food was very spicy and extremely cheap, around 75% cheaper than in the restaurants near touristic attractions, quite frankly it was delicious!
2. Where as in the UK you have to pay 5 pence per plastic bag, in Thailand you will get hundreds of them for free. Plastic bags are used to pack everything starting from groceries, cold food, desserts, warm food, your ready to go soup, and even drinks poured straight into them from the street market.
3. If you do not speak Thai, that's ok. Visit Phuket to practice your Russian.
4. Sea water again from the shower... I am not going to mention how much my hair and skin did not enjoy showers. I was not ready to taste like a salty chip yet there I was. Salty, and sexy or not, and sun burned on Phi Phi.
5. When you are in Bangkok, feeling like a king because it's the beginning of your trip, splashing cash for taxis and tuk tuks because walking 500 meters is too much to handle in the heat... You can save that money for later, buy a magnet for your mum or another overpriced thing, and instead take a public bus. Yes, I mean ordinary city transport with people going to and from work. Instead of 100 baht or however much it cost to get to MBK for a taxi, be a smart cookie and save money instead, and pay only 7 baht for a bus. To make it easier, on your phone have the Thai name of the place you want to go to. The travel attendant, who you buy your ticket from on the bus, will tell you when you have to get off for your stop. They will either speak English or tap you on your shoulder when it is time to leave.
6. Coral reef are sharp, very. Probably more than you think. I knew they were sharp, I just did not expect it to be so extremely sharp! Actually, it is so sharp it slightly made me freak out when I noticed how my travel companion accidentally cut his feet.
7. Monkeys are strong, and aggressive, and very protective over their little ones. They also steal everything, anywhere, and from everyone. So if you want cute photos from the Monkey Island near Phi Phi take extra watermelons with you and hide your Go Pro or hold onto it very well. Monkeys seem to love watermelons and stealing gadgets! Everything for a cute photo, right? I actually just picked up a leaf. Even if you are a buffed dude, monkeys don't care, they are still stronger. I actually have a video of a monkey robbing a guy from my travel group. His face expression is priceless, so hilarious.
