@ mwenza,
although this was not about beers if you ventured into the bars and night clubs in Eastleigh, ziwani, pangani, riruta, satellite, dandora umoja etc there were joints which used to be called class Z...this is where the beer was going for that amount, around 3.00....actually i took my first bottle of beer (tusker export) in eastleigh in 1988 at 3.20 while my collegue took his guiness at 4.50...
...besides, the presence of a safe alone does not signify that there is money inside...
