They may have took the huff Mocas due to your lack of hospitality and may never return!!!
They're back.
Always offer them tea just to keep them on site so the job gets done, you could even take the tea up onto the roof yourself and inspect the work quality!
I'd be worried if I thought that a supply of tea would make the difference between the job being finished or not. And I have no intention of going anywhere near the roof!
