I used to hate this when I did price work for builders or customers who are running their own job,first fit usually Ok ,then you arrange to go back for second fix and tiler,joiner or who ever has not finished there bit,not necessarily their fault,but builder or customer expect you to sit about for 3 or 4 hours if you are lucky,while others are ready
In the end they would ring me and say ..Am ready for you on Wed and I would say,booked up till Thurs,a day later,still sometime they were not ready,never ring,trouble is ,they want the job done asap and expect us to que up till we can get in
Also used to hate it when they would book everyone at the same time to work in the same area,expecting 5 blokes ,with all there stuff to work in a small bathroom or kitchen ,like 60 min make over
After saying all that,hope you get in and finished asap nysk and get hold of ya wonger for the job
