I was actually told a couple of times to walk slower, no one was in and they were trying to stretch their fs time to the minimum one hour, then we'd end up going to a garden centre for tea and i used to hate all that waste of time. When the ministry finished i'd rather go back home thanks and get on with stuff, esp as one sister used to put her bible in the middle of the table in the hope to attract passers by i used to cringe!
Also my mil used to do return visits but she'd deliberately pick out one or two where she knew she'd be invited in for coffee so that she could be there for longer.
I used to say to hubby if they really believed it was the end they'd all be pioneers, out speaking to people as many hours of the day as they could, but in our congragation it was do an hour, then have a coffee and a few rounds of golf!
