Pickpockets are in every country. Be careful of pickpockets active in the area of St. Stephen’s Cathedral (Vienna) and on crowded streetcars (trams) and subways (U-bahn) Some work in pairs or sometimes in threes. Some organized bands have been known to use children, too, in their work.
Stand to the right on an escalator in the U-bahn or elsewhere. Let those in a hurry go on the left.
Let those getting off public transport depart before trying to get on.
Observe seating in public transport designated for the blind, old, sick, pregnant etc. A decal next to these seats, which are usually next to the door, will identify them.
Observe “Keep off the Grass” where signs request it. Keep the place green for the next visitor.
Buy a ticket for public transport. While it is an honor system, inspections do occur. Inspectors have heard every excuse known to man and will still give you a high fine.
Use facilities to check coats at events.
Get smartly dressed for the concerts and operas or clubs and fine dining restaurants.
Expect to pay a small sum (50 cents) to use some restroom facilities.
Expect to pay cash for services in small restaurants and hotels.
Watch where you walk. Vienna has many dogs; they leave their greetings in many places.
Let old Viennese ladies move in front of you everywhere — if not, they will probably push their way in front anyway — a tradition.
Tip the waiters/waitress after your meals; not necessarily 10% of the total but you can round up to the nearest Euro.
Expect to be chased out of the shops 5 minutes before closing time.
Expect Austrians (and Europeans in general, except the British) to respect the custom of waiting your turn in line. People will sometimes try to push past you, but a stern look right in the eyes is enough for them to retreat and needs no translation.
Expect everyone to speak English.
Expect every place to have air-conditioning.
Expect ice water
Expect English-language menus in all places. Your waiter can usually explain everything.
Expect to find diet drinks and non-smoking areas everywhere.
Expect waiters to bring your bill after eating. They will present it only when you ask. Many here will sit for some minutes talking after finishing a meal.
Expect stores to be open late evenings or Sundays; on weekdays, most stores close at 6:00 pm (except in the 1st District) and on Sundays, all stores are closed.
Make noise after 10 pm (except on New Year’s Eve!).
