Most Austrians would round up the amount. Hence, Euro 2.25 would become Euro 2.50; or Euro 64.50 will become Euro 70. One will not offend if one simply "rounds-up." I do think that excessive tipping seems rather frowned upon. I doubt the receiver of the tips will complain but I think it is seen as a bit showy if you give a big fat tip. So, you will just have to play it by ear.
I would usually give @10% tips, unless the service was horrible.In restaurants and bars, the service fee is not included in the total bill. The waiters/waitress will expect around 10% tips.
For others - in general - you can give 10% - 15% to taxi drivers and hair-dressers. Porters may expect about Euro 1 or Euro 2.
