So many really but a quick list:
Old people driving
People who drive via satnav and satnav only
Neighbours who talk about each other and make you think they're not talking about you
Telesales
Door to door sales
Gyppos when scraps high trying to get my Cossie for free
Busybodies
Blatant liars
People who cant use self service tills
People who book things in then never come back
The labour government(well DID)
poor spelling
Text speak in anything other than text

There's so much more but I've got a kitchen to fit!!!!
