Similar thing happened to me with both Facebook and LinkedIn. I visited a bank and spoke to an employee for about 10 minutes about opening an account for my business. My location was switched off and at no point did we exchange numbers. A day later, I saw that particular employee in my suggestions on both LinkedIn and Facebook We of course had no mutual connections at all
