There's a wonderful Facebook page called "Overheard in Waitrose" where shoppers post surreal snippets of conversations such as, "Tobias would you fetch mummy a packet of Waitrose Essentials Macadamia Nuts." I am thinking of setting up a rival page; "Overheard at the Phone Bank".
Here is tonight's gem
"Oh, you'll be in Phuket on 7 May. Do you have a postal vote. Oh, OK. You travel to Phuket six times a year? Really... that's a lot. What takes you out to Thailand so often? Oh my goodness. No No No - I don't really want to know any more."
I am pleased to report the respondent was not a Conservative pledge.
