Since it's a local (a possible branch) hardware store, it's POSSIBLE BUT VERY UNLIKELY: PROOF: Assume 100 clients/day are buying from this store, that means, 3,600 customer a month or 43,200 clients a year. The one-millionth customer will occur after 1,000,000/43,200 = 23 years. or it will be after 46 years if the average customer is 50/day. So it is possible but MOST UNLIKELY
