Use a Straw!
I have finished my NEBOSH course now. Well, the learning, the exam is on Friday.
One of our lecturers/tutors has done a bit of work in the brewery industry (nice work if you can get it… although apparently they only ever offered him tea and coffee) which leads to a strong suggestion that one should not drink beer from the bottle. Bottles of beer are stored in cellars and out houses and places like that. Its not unreasonable to say that a number of these will be visited by rats, and rats like to pee.
Leptospirosis is spread by rat pee.
So, his choice is to always ask either for a glass, or a straw.
Mind you, who would drink softies out of the can either?
