Tried to buy propane at 9pm and was told they only sell propane from 6am to 6pm. Cashier was friendly.
Update: Conoco responded to my review and advised they are in between evening employees able to handle the propane. They will soon have an evening person available to sell propane and offered for me to contact him after 7pm until the staffing issue is resolved. Will reach out to him tomorrow and see what we can work out. Customer service seems to be a dying art so it is appreciated when encountered. Changing my rating based on that.
