OK I'll go first...I'm going to make a big assumption that we are using the stores as standins for dance organisations???!!???
I will add I do NOT know exactly what might have prompted the (perfectly fair and sensible) question so am not secretly putting up someone elses view
Not IMHO a suitable analogy in the way set out here, reason being, supermarkets are used for necessities, requirement for which will be a fairly finite amount per person. So shopping at one store, as suggested, means less shopping at another store.
But, IMHO, dancing in Scotland is not a staple product but a luxury product so purchasing from one vendor does not preclude one from purchasing from another vendor AS WELL. Particularly if the products are slightly different and offer different experiences.
Hope this is slightly clear.
