“I don’t think it is an apt analogy if they don’t normally serve beef (for example).”
It is apt.
The bakery does not normally sell the product in question either.
The Indian restaurant does not sell beef due to religious principles.
The halal butcher shop does not sell pork due to religious principles.
“The bakery does not normally sell the product in question either.”
The problem is, in many of these cases, the bakery (or florist, etc) DOES normally sell the product in question.
It isn’t apt.
The bakery does normally sell the product in question (wedding cakes).
The Indian restaurant does not sell beef. It does not matter why.
The halal butcher shop does not sell pork. It does not matter why.
“It is apt. The bakery does not normally sell the product in question either.”
Uh, the bakery sells custom cakes for weddings. In fact, they had previously done a cake to celebrate the wedding of two dogs!
Doesn't sell wedding cakes? Yes it does. For your analogy to be accurate you would have to go to a bakery and request a steak or the Indian restaurant and ask for a screw driver.
