I have the classic LL problem of bunged-upness and was told by my LLC to up my water flavourings. I am v secret squirrel about LL at work so measured the flavouring out into a twist of clingfilm to pour into my water bottle in the office. It was only once I'd walked past 4 police officers with sniffer dogs that I realised that I might have had some tricky explaining to do if they'd done a bag search as to exactly what the white powder was!!
