Back from client number two. No messages either phone or email from the computer shop so looks like next week. It's possible that the drive has arrived but they'll contact me when they can do the work straightaway rather than just leaving it there for when they can. It's not as if the computer has broken down.
Arranged with another client to see her tomorrow morning. I had already done the work and was going to wait until my computer was done. But I thought I'd ring her and see if I could see her briefly tomorrow. She was in "deepest darkest Herefordshire" (her words) and her mobile reception was poor. Hopefully she got what I was telling her before the reception gave up all together. I've sent her an email anyway. The client I saw this morning, the "client who lives in the middle of nowhere" currently lives in Worcestershire but has lived in Herefordshire so I know that things like mobile and internet connections can be tricky in places.
