TheCatsBollocks - you obviously have some bug up your arse about cyclists, who, I can assure you, don't think they have any more right to the path than you, and you are projecting.
If there are people on a shared path, with or without dogs, then I will have to brake in order to pass safely whether they move or not. They are causing me inconvenience, but I accept this is just part of using a shared pathway. If they move out of the way, then I will thank them, as I am causing them an inconvenience. However, I will bet my bottom dollar that it would not occur to a single one of them to thank me for slowing down in the first place. They (and I) just accept that my behaviour is right and necessary for everyone's safety.
In my opinion, the same applies to dogs - an uncontrolled dog is as much as danger as a speeding cyclist, and calling your dog back under control is right and necessary for everyone's safety, not a special courtesy deserving thanks.
How about we all just accept that we are all inconveniencing each other, thank each other or just accept a smile and nod as we go by, without anyone getting all upset about perceived slights or feelings of entitlement?
