Make sure that the taximeter is active at every cab you take. As long as you stay within the same district/city, a taxi cab will never cost more than 100 ₺ (~15 €). If a taxi driver asks you that, refuse and try asking a local if you can. If they are getting aggressive about it and you're sure you're being scammed, make a scene. Learning how your currency converts to Turkish Lira can help as well.

Don't give money to beggars, especially if they jump in front of you or try to sell you stuff. They likely have more money than you anyways.

If you don't go out of your way to see notoriously dangerous places, you'll be fine. Messing with a tourist is one way to get in trouble for a local, so if you stay in touristic areas you won't be in much danger compared to your country of origin. Just don't try hiking to the middle of nowhere in Southeastern Anatolia and research parts of the city you're visiting. r/Turkey is a good source.

If a Turkish stranger invites you to their house after talking for half an hour, don't freak out. We do that to everyone we like.

Istanbul is the place you go to for most of the thingies. To see the best of the thingies visit other cities. Also avoid Istanbul if you don't like crowds as it's a tourist trap. Try places like Rize, Edirne, Bursa, İzmir, Nevşehir, Hatay, or Denizli instead.

If you go to Ankara you might be disappointed, it's just a big businessy city with nothing really touristic. If you're not looking for a job don't put it on your list.

Falafel ain't Turkish food

Turkey doesn't have native camels. See that camel in front of your hotel? Someone bought it. You paid to take a picture with it? Congratulations you got scammed.

Apple tea isn't an authentic Turkish thing, we just give it to kids and tourists because Turkish tea is bitter. If you got regular Turkish tea, don't ask for milk of they'll call you a gavat behind your back.

Foods to try: Midye dolma (stuffed mussels), yaprak sarma (vine leaf rolls), balık ekmek (fish sandwich, literally "fish bread"), testi kebab, kısır (some red salad thing idk), cağ kebab (like döner, but tastes good), mantı ("Turkish ravioli" that actually evolved from Chinese dumplings), künefe (some cheese dessert thing), lokma/halka/tulumba tatlısı (actually the same dessert in different shapes but we don't want to talk about it), sand (when we get hungry in the desert we just scoop some up and eat it), tavukgöğüsü (chicken pudding (chicken pudding (chicken pudding))), Maraş ice cream (ice cream but the seller bullies you), eşkışkın (famous taste™), pastırma and sucuk (pastırna and sucuk)

Beverages to try: Salep (fancy places sell real salep, fake salep tastes like baby puke), Niğde Gazozu (soda brand), milk (most of Turkey is lactose intolerant but we drink it anyways to flex on Europeans), Beyoğlu Gazozu (another soda brand), şalgam (if you're brave enough), Turkidh coffee (which is actually finely ground regular coffee prepared in a Turkish style)

If you have working taste buds, avoid anything with Çamlıca written on it.

If a dog has an eartag on, it is safe to pet. If a cat exists, it is safe to pet. Some people like to be pet as well but you'll have to find them.

Please don't hit on strangers, it is taboo. Except certain places like bars. If you try to catcall a woman on the streets, you will likely get beat up. If strangers catcall you, make. a. scene.

No, we can't translate Arabic. You are more likely to know Arabic than an average Turk.

Do not ask people about politics. We don't talk about that to strangers and it is the best way to ruin everyone's mood.
