This occurred at the Gulf Coast Town Center location on 6/27 and one of the customers targeted said: "To give Costco the credit, they escorted him out and made me wait inside and monitored him until he left and then they send someone with me to the care to make sure I'm okay."

What's even more interesting is that tan(int) is *not* a random number generator. There's fascinating patterns in the data. One way to look at it is: if tan(x) is very high, x is very close to a 90' or 270' angle. So if tan(x) and tan(y) are high, tan(x + 2y) is also high.
