Walmart stores in the Greater Vancouver area of Canada do not have a button. A customer wanting to buy baby formula has to walk around the store to find a staff member who might know some other staff member who has the key.
The customer is then required to be accompanied by the staff member to the nearest cashier to immediately pay for the item before continuing shopping.
