Danish pastry you stupid Swede!

We were on holiday at Bornholm an island which belongs to Denmark.  We went to a bakery to eat something nice. We ordered coffee and the lady asked us something which we did not understand as it was in Danish. As we did not understand she asked us again in a higher tone and we still did not understand so she almost screamed. - One or two coffees? As if that would help.  Then I pointed to some cakes and said I would like that croissant. The lady got angry and screamed. -It is not a croissant it is a Danish pastry!!!
