Was on a train once and heard a phone go off behind non stop to indicate text messages. Nothing unusual about that, I caught the odd phrase like "are u free today" and "where are you based".
Turned around and saw he was using a Shitty £10 phone. Yep he was a punter. A stupid punter.
Another time I was having a drink in the local, grabbing last drinks I noticed a guy looking at his phone, I peeped the words "1 Spanish 1 Italian" as I sat down I texted the local parlour about which girls are working, got the "1 Spanish 1 Italian" reply
. I'm going to guess he might of messaged to same parlour.
