If you have a choice, never buy an ice cream from ladies with large breasts, you will get a bum deal.
I have researched cone icecream servings in depth over the past year and noticed that some lasted ages, others were gone in a flash.
I developed a means of consumer research, and a complex equation, using velocity, (kilometres per hour), average licking rate,temperature,etc.
While I am still working hard on this complex problem, I do have some preliminary results.
Males tend to serve a fairly average ice cream, there seems to be little variation.
Females on the other hand, serve wildly different sized ice creams.
Females with small breasts nearly always serve bigger ice creams than those more amply endowed.
My research continues......

I wonder if the same applies with male hot-dog vendors?

Or doughnut sales ladies.
