Do I have to tip when I buy a calling card in Germany?

Tipping in Germany is not an obligation that consumers must fulfill, but a voluntary gesture of affirming service and expressing gratitude. You can choose whether to tip according to your own needs. In Germany, catering, beauty salons, taxis, hotels, moving, decoration and maintenance industries are common industries for tipping. Generally speaking, the tip in Germany is about 10% of the consumption amount, so it is necessary to remember the principle of topping up.
