First come, worst served? A titbit from the Vending Lab

Did you know that the first drink served after a canister refill could contain 14% less ingredient than the remaining vends?

Becktech put some components through their paces in its Vend Lab and discovered a consistent, and considerable, variation in the ingredient throw following each top-up of its canister. Food for thought?

Perhaps a dry vend following any canister top-up would be worth the trouble to prevent customers being short changed.
