Shoppers Drug Mart worker Mark Oliver sends sci-fi reply to customer TORONTO, June 6 (UPI) -- A Toronto drug store chain employee who sent an email purporting to be from the future to a customer said he was hoping to brighten the man's day. Mark Oliver, an employee at Shoppers Drug Mart's Toronto headquarters, said he thought Andrew Gardener would enjoy his sci-fi inspired response to Gardener's email asking to be removed from the company's mailing list, the Toronto Star reported Thursday. Gardner's email speculated on why his address was receiving mailers for a man named "Matthew." He questioned whether "Matthew is a future resident of this address, and seemingly against the laws of causation, your computer system has this information and prematurely mailed an advertisement to him before he's actually lived here." Oliver's email confirmed Gardner's suspicions. "Unfortunately, we cannot comment on any research projects that we may currently be conducting," the reply read. Oliver detailed a made-up cancer-curing product and touted Shoppers Drug Mart as "the ideal place to hold up and hide from the hoard," but "Blood samples will be required for admittance." Gardner said he was pleasantly surprised by the email. "[The email] read like customer service speak," Gardner said. I actually closed it and put it aside. I looked it again and I said, 'Oh my god, this is hilarious.' Oliver said he did not expect the email to go viral online. First, I thought it would be one person reading a joke and a little bit delighted to have it. I didn't expect to be about 30,000 people reading a joke. And the other thing is I'm leaving the country in two months so I thought the consequences wouldn't be too bad," he said. A Shoppers Drug Mart spokeswoman said the store was happy to make Gardner a "satisfied customer."
