as i working as a researcher, i did a survey and there are 2 types of machine serving nescafe tekan2 in the market currently..
one of it is the nescafe machine similar with the one we already have in our library.. but this one doesn't have the vend! how can we make money with this? and it needs daily maintenance including refill the nescafe/coffee/milo/tea and wash the tray.. otherwise, lipas might hurung and habeskan our milo before we did.. the problem is, our crashlab is not even near to the HQ and not everyday got people there.. hurm2..

the second type is the real vending machine with cup.. this one i haven't try, the taste and the maintenance system.. so cannot comment more on it.. hayyo.. anione have any idea?
