I'm in the Middle East and some things have already been mentioned.
Car seats have only recently been made mandatory. I used to get a lift to work from a lovely Arab family with two small children, both of whom would just sit in the back seat of the car with no car seats, no seat belts, while we whizzed down a motorway (with drivers overtaking on both sides, swerving across multiple lanes etc). It was nerve wracking.
All the wait staff are unbelievably nice and helpful. They get paid peanuts by our standards but they are just so genuinely lovely everywhere you go and nothing is too much trouble.
Everyone wants to hold my son. Strangers even try to kiss him! Some of them tell me about their own babies back home - a taxi driver a few days ago told me he won't see his little son for another eighteen months, and I've met numerous fathers who have never met their children.
Arab mums used to castigate me for not wrapping DS up properly. It was almost forty degrees outside! If I'd put a blanket on him he would have baked like a potato! It's not unusual to see local babies wrapped in cold weather clothes and layers of blankets, even though we literally live in a desert.
Brunch is a weird thing. On Fridays (weekend here) you go for Brunch. it could cost up to £100 depending on where you go, but there are dozens and dozens of them in the city. It starts at 12 and generally finishes at 4 and it's basically an insanely massive all you can eat/drink buffet. Everyone leaves their homes at 11:30am, dolled up (sometimes like they're going to a night club if it's a 'party brunch'), and gets absolutely shitfaced over the course of the afternoon. Then you can go to a post-brunch party, kind of like clubbing, and be home by 8pm, completely wasted.
