Heni you will get used to it here, things seem to operate differently and it will be a new experience for you. Everything cant be the same everywhere now can it? You are free to go and make your own tea if you like, but normally every big company have their own kitchen with have people to make your tea and bring to your office.

You can park your car outside any grocery and honk and you will get ur stuff delivered to your car, you can tip the petrol guy if he wipes your windows, mainly i do that in Waqood petrol station.

Besides all that you are free to give anyone as much tips as you wish no one will refuse it ;)
