Done a lunch time 15 minute quickie punt a couple of times but there are a few pitfalls -
I can't book in advance as i'm likely to get a call saying i'm needed in a short notice meeting or conference call etc so need to disappear to my car for lunch and put a speculative call in.
My choice of lunch time parlour is 20-25 minutes drive away so need to allow 30 minutes in case of traffic (having already checked the AA traffic news before calling).
Quick pump and dump then out the door with no time for a shower so skip the massage / talc / oil otherwise you walk back into work reeking of whore
Back into work about an hour and 15 minutes after leaving however I only get an hour so can't clock out, hope and pray there hasn't been a fire drill or yet another false alarm while i've been away
Sit back at my desk feeling de-stressed and laughing inside that nobody knows what a dirty bastard I've been less than an hour ago
