Yes I completely agree, having very similar notices and messages on my phones and door I find the level of entitlement to be quite staggering at times. Obviously that doesn't apply to them - and I must be the stupid one if I'm not interested in talking to them! Also, at the door, the insistence on hammering when the dog has already barked to let me know someone is there - and then hammering again all of a minute later if I've not got to the door yet, causing the dog to bark even more. My partner is house/often bed bound, I'm his carer despite my own various health issues, the signs/messages are there for a reason, the dog will only bark a couple of times to alert me if people follow the (polite) requests, but apparently that's too much to ask.
