It seems that a misfired maroon recentlycleared out the cakestand in a Cornish cafe .... frightening. However, the RNLI says that not only is there an H and S issue, not using maroons will save them £50k a year. The locals here in Weymouth are v upset but since no-one else has responded to your post of over 2 weeks ago, maybe no-one here cares!
