B****y hell

How on earth did us 'old school' window cleaners ever manage before computers were invented :

I have a round comprised of monthly or two monthly jobs.
I list them all in the order they should be done on A4 sheets laid crosswise (landscape in the modern vernacular). Across the sheet I have 12 columns. If a two monthly job is not due, I put an 'X' in the column. Every day I write a list of the next jobs I want to do, in their right order. I go out and do them, and tick them off on my list. Those who pay get a tick, those I intend to collect get a 'C' those where I leave an SAE get an 'E'.
When I get home I update my 'office copy' from the records on my list - at the top of the column I put the date cleaned, going down the column I put the ticks, 'C's and 'E's.
At the end of the week I go through the list and pick out all the 'C's - that's my collect list. Any SAE's that come back I cross out the 'E' on my master list. When I've finished collecting I cross off all the 'C's I've collected, or if they weren't in and still owe, I put and asterisk, so in future I know I've tried to collect but couldn't.
All the information I could possibly want is there in front of me on the same master sheet, with the history of each job
How can you possibly miss a job if it's in front of you in black and white?
Running a window cleaning round is basic, simple routine. If you can write, you can keep infallible records.
The thing I don't like about computer programmed round records is that they can't handle the fact that weather, odd days off etc upset the routine. If you have a mix of monthly and two monthly jobs, then the program will re-schedule exactly 4 or 8 weeks into the future, so any two monthlies will be out of sequence from their geographically related monthlies.
If they're written of a sheer of paper they're still where they're supposed to be.
I've yet to find written records jumping off the page and reappearing three pages further along
