Go to the bar

There's a rather fantastic collection of home made slot machines to be found on the pier at Southwold in Suffolk.

Given their uniqueness and their acknowledged temperamental nature, there's a sign to use the intercom for assistance.  That's supplemented by a delightful postscript..."If no reply go to the bar".

That could of course mean that at the bar you shall find pier staff to assist you.  Equally it's somewhere just to go for a drink to cope with the any disappointment or frustration.  Or even if there's no-one on the intercom, it's because they've themselves gone to the bar. I suspect that the interpretive licence is intended here. Love it.
