I recieved an interesting new terms and conditions from my bank

In part it states
"Although we have no intentions of exercising this right, federal regulations require us to reserve the right to require at least seven (7) days written notice prior to withdrawal or transfer of any funds"

I doubt it is some conspiracy, but it is a strange thing I never noticed. I never really have any money so it makes little difference to me, but it made me go hmmmm
