For me, on cashing out or withdrawing my money from my bitcoin wallet, I preferred to use directly my bitcoin wallet for payment to store or shop so the fee will be less for and worry not on handling money on my own pocket. Because I believe transaction fee will be the same, withdrawing the money by yourself or sending money to store or shop you preferred to use to. Just be secure on sending it to their account.
But then when the bitcoin users increases maybe there will be a chance that the fee of transaction on bitcoin will decreases, because the more users will be the more chance to have lesser transaction fee.

This is just my point of view.
Thanks,  just respect.
