"PUB SESSION

Tip jar."

This seems to be a rarely recent phenomenon with which I have great reservations.

Firstly, it is an excuse for the bar management to pay a mere pittance to the musicians in the case of so called "paid sessions".

If the session is unpaid and the musicians are playing for their own amusement and enjoyment, why should they expect payment? Passing around a "tip jar" is akin to busking if not begging, in my opinion.

If the punters enjoy the music, they can always offer to buy the musicians a drink or put some money behind the bar for this purpose. This is a lot more sociable!
Of course, many sessions are now full of tea totallers these days but surely they can still accept a soft drink or even a cup of tea or coffee if offered? Rather than seeking pocket money.....
