I like your policy. My wife’s shop used cheap rental gear for classes. The open water check outs were to be in Cayman, when I asked about her using my travel weight BP&W they said absolutely not. Despite them being a NJ shop they didn’t sell BP&W’s and didn’t want their students seeing them.
Turned out to be a non-issue when their DM hit my wife with an AL80 and she lost faith in their shop. We still went to Cayman, I dove and she snorkeled.
