Input: Consider Input: Our baby is too small to eat adult's food, so we bring our own baby food with us when we dine in a restaurant, which supplies us with a baby high chair.

I am wondering if it is rude to bring our own baby food into a Korean / Japanese restaurant in Australia?


Output: Is it rude to bring our own baby food into a restaurant?


Input: Consider Input: While traveling in the EU, with both a Visa and Mastercard issued in another country within the EU, does it have disadvantages if both the cards are debit cards?

Would one need a credit card for the sole purpose a debit card is not accepted but a credit card would be?

If ordering products online from a EU country, are there possibilities of credit cards being accepted and debit cards not?


Output: When traveling in the EU, are there significant differences between paying with credit or debit cards?


Input: Consider Input: I'm really lost trying to understand the tariff for Nuremberg (Nürnberg) public transport. This is the most complicated thing I've ever met. 10 tariff zones and a dozen of ticket zone variants...

Let's say I'd buy a periodical (weekly for example) ticket for Tariff A (zones 100 and 200, Nürnberg, Fürth and Stein). What ticket do I need if on single day I'd like to travel to, let's say, Erlangen (zone 400, zone 300 is crossed). 

If I'm going to stay there the whole day and use multiple buses etc., do I need to buy daily ticket for 4 zones, or can I buy some kind of supplemental ticket for zones 300 and 400 (because I already have the ticket for zones 100 and 200)?



Output: What kind of ticket is required to travel to other zones having Nuremberg periodical ticket for tariff A?
