Just flew the JNB-DOH-FRA route. On the JNB-DOH, there were hot/cold towels offered but NOT on the DOH-FRA route. Guess this has to do with the 6 hr. 15 min. cutoff. Also, candles were offered on the longer JNB-DOH route but not the other. Trays were still used on both. Otherwise, the excellent onboard Business Class service is indistinguishable.
