This Dublin bar could really be onto something, lads.

An intern at Oscar's Bar in Smithfield, Dublin, was messing around with the till and added a genius new function – the Hipster WannaB Surcharge.

Refuse to drink anything that's not served in a Mason jar? Have a man-bun? Wear thick-framed black glasses even though you have 20/20 vision? That'll be €2, please.

We know the folk in Oscar's were only having the craic, but we reckon this could really catch on. Give this Ronan fella a promotion, quick!
