I visited a sandwich bar during my lunch break and noticed an addition to the in-store signage taped to the drinks machine:
NO FREE REFILLS!!
Why not? The product of post-mix soft drinks costs about 50c a litre. Selling a 400ml cup for $3 allows for plenty of room for profit. And how much could the average consumer drink? 2 refills, max (1.2L)? And what about the point of difference from the sandwich bar next door? Now you are exactly the same.
And if you are adamant that you can not provide free refills, I am sure that there is a far more courteous way to advise the lifeblood of your business that this is the case.
