Popa you can’t be serious about that.
1. I suspect American Express does this specifically because their merchant fees are higher than other cards, and this is the sort of thing that convinces small businesses to accept their cards. This logic really doesn’t apply to Yeshivas.
2. Even if that’s wrong, and we’re talking about a company, so there’s no reason to think that logic is any more wrong or right than any other, it’s really not for the Yeshiva to decide what American Express’ intention is. This program was clearly meant to support small businesses. Yeshivas are not small businesses. A yeshiva telling American Express that it is a small business is dishonest.
