Lechatnoir Wireless headsets aren't expensive lol seriously for the rich? Don't be so dramatic. You just don't want to carry another bit of kit. Its hardly massive!
Talk about 'Let them eat cake!' I invited honest opinion, not sneering. 
Punching down invites reciprocal punching up.
£30 is a lot here, and there's nothing left to cut. Currently I'm in flip flops because I can't afford the footwear required to fit my feet and braces.
You have very little idea what working in a wheelchair is like, how little some end up with after additional expenses, or how much I and others already have to carry in a very limited space.
You're right that I don't want to carry anymore kit without a place for it, I honestly don't know where or how to add anything more that isn't tiny.
I'm an embarrassing failing disaster area already wearing two bulging bum bags of kit, and lots hung off my neck as well as a drain bag on one thigh. Tubes coming out of me catch on things, and I struggle with breaking things and losing things as zips come undone struggling to get doors open and pulling myself up ramps by handrails. (designed to be pushed up not self propelled up) To add to it my wheelchairs too heavy for me, because I can't afford the contribution required from me for the right one. I suffer bruising and rubbing from much of what I have to carry.
I don't feel able to carry any sort of hand bag or rucksack having had three taken off me, (one violently even though I hadn't argued) and have to have a crap phone that muggers cant be bothered with. I'm not seeking pity, just some understanding of what my existence is like.
Yes I'm being selfish in a world that generally is, but I am listening and do hear you about how annoying you find it to have someone on speakerphone on the street. Currently I'm not seeing much I can do about it, but I didn't realize it was such a deal, and have learnt and accepted from this thread that for some it really is.
So please hear me; however annoying you find it all, there's nothing "dramatic" or to "lol" about someone not being able to manage financially or physically what others get to take for granted.
