travelling short stops by the door

this weekend, among other things, i had to arrange the breaking of my mobile contract from home (which disabled the use of my new local SIM card until now). took me two hours since they could barely break into the system and at the Nth attempt only, so even the price was lowered. on my way there i was using the Bahn for a few stops and suddenly two people entered at the door I was standing at, and both shouted suddenly and simultaneously. the one´s pronouncement was MUSICA! while the other said FAHRKARTEN! - and in line with their announcements, the former started hitting his guitar and singing while the latter went around to check on our diligence to pay.
