Many COs would only want to have lunch Wed, Thurs, Friday. That way they could keep Saturday afternoon to themselves. (Not sure if that was officially OK or not, but many COs did this.)
Anway, my wife is a fantastic cook who really enjoys great food and wine. We got this one young CO and his wife who had just gotten into the traveling work. We had them over for one mid-week lunch and hit it off really well. For all their remaining visits, we suggested they join us for Saturday lunch so we could enjoy some good wine(s) with our meal. They were happy to take us up on the offer. The PO arranging lunch schedules would always ask us if we wanted to take a mid-week slot, and we'd always discreetly decline saying we had already had the "privilege" on their first visit. I think it really pissed off the PO, who was a real Circuit/District power player, that this CO and his wife enjoyed hanging out with us relative nobodys.
Other COs over the years were a mixed bag.
