We have 31 flavours, just not today

 Baskin Robbins is known for having 31 flavours. In the film Ferris Bueller's Day Off the ice cream chain is referred to by the number alone.

But ice cream is a seasonal business with much higher demand in the summer. I was killing time between ferries and went into the Baskin Robbins in Horseshoe Bay for a cone. This location has two coolers with a total capacity of 32 different flavours of ice cream, but in the winter the selection is reduced with only 16 flavours on offer.

I can understand the desire to reduce inventory during the slow months, but it does make a bit of a mockery of the firm's branding. The logo even includes the number 31 in pink.

Just another one of those things that few people notice but that annoys the pedantic observer.
