Fritz Rathke set up apt today for 3PM (note: he was in the area
sunday with friends so suggested he come by to look)..no response.
Monday..phoned at 4:15 to chk on arrival....5 PM Fritz called, said he wasn't coming. I suggested when he returned home to rebook. 7PM Fitz phoned & advised 3 weeks was now his best apt. Conclusion:this does not appear to be a organized or realable source for plumber service.
