The operator on the phone was rude and very impatient. The connection was bad and as he could have told by my German accent and my constant back queries, I had difficulty understanding him. But he didn't bother slowing down or speaking up or more clearly, he just became impatient and rude, talking to me like I was retarded and not a foreigner in need of some help. He finally hung up on me without a word of goodbye or acknowledgement, so I had to call again to ask for the waiting time.
The cab came on time, and there was no fault about the ride.
