I've spent many years selling various food products on stalls in food halls at shows. The general public have to be seen to be believed, the way they can behave over a free sample...........so those stirring sticks - someone licks the food product off it, what if they then stick it back in for another try........? They abandon it on the table........someone else in their greed will then pick it up and stick it in the pot
I never try free samples...........seen too much from the other side of the counter.
In the US the 'Honey Straws' are sold as sweets - the system fills up plastic tubes that are then heat sealed , you cut the top off and suck the contents out. They also use them as 1 portion packs for catering too.
I've never seen them or the filling machine in the Uk before !
