Archie, Carmen, Mr F and Elvis

The drivers side window on our car went down and wouldn't come back up again, so Mr F dropped Carmen and I off with Elvis and we collected Archie for a walk.
He met us near the end and took over walking Elvis while I drove back to our starting point as Elvis walks so nicely for him and he doesn't for me!
Later Mr F was given a loan car which wasn't a loan car at all and had been sold, so the garage telephoned and asked for it to be returned and swapped. I think the trouble is that the boss is on holiday and nobody seems to know what's going on!
