If there is a wait in SEN Z, I would go directly to SEN A (get through passport control) and see if there is a shower available in A within a reasonable time. In either case, if you stop for a shower, there will be little time left for breakfast, so I would either eat on the arriving flight, or plan to grab something very quickly before heading for the gate, or wait for whatever sumptuous short haul tray is presented on the flight to ATH.
