hitting the bottle with a brown felt tip

To hit the bottle with a brown felt tip or hitting the bottle with a brown felt tip is a form of traditional glass beer bottle tapping common in the Seaside Town of Bridlington, East Yorkshire in England UK. Amber or brown glass beer bottle tapping is locally known as tapping the glass or hitting the bottle with a brown felt tip and implies quite simply that one, when ones' glass (or bottle) is empty quickly taps the side of the glass or bottle (with a brown felt tip pen) to give notice audibly to anyone in range that another beverage is required by the tapper. Landlords in Public Houses in Bridlington now insist that only brown felt tip pens are used for bottle hitting. The reason for this is that if the ink end of the felt tip were to touch the label (or glass) then only a brown mark would be left which may (or may not) blend in with the brown glass or commonly used cream/brown labels. Vulgar colours such as Purple, Pink and Yellow are frowned upon and usually a tappee (one who taps) would either be ignored or escorted from the premises for failing to adhere to the appropriate colour code. Quite often one may see the sign "Tap Room" as one enters (or leaves) a Public House in Bridlington. Tap Room is (of course) a simplified version of "Tapping Room", easier to read when driving by in a hurry or when not quite sober and visually wonky.
