Yes, but the descriptions of the establishments in question are clearly fictional if the Mullion Cove cafe doesn’t have a letterbox or serve panini, the Westward Ho! pub has never had a quiz night etc. That’s what the owners and the former manager of the Treen campsite are objecting to, being fictionalised negatively.
(Though the instance from Kinlochbervie is a bit misleading, anyway, because even though they’re not allowed in, acc RW, the staff member comes outside to serve them at an outside table, explains they’re trying to stay clear of Covid, and is perfectly civil, and helpful — she’s the one who confirms the Cape Wrath trail is closed and suggests they camp at Sheigra.)
