Do all AD's have guards with guns?

[joeh]

Walked into one AD and there were two very large guards with guns that stared me down after I passed two doors one at a time. While looking at a watch, the salesperson asked one guard to stand next to me. Another AD just had one pay duty police officer. Pretty intimidating shopping experience for sure.

When I walked into a Cartier store in Paris, there were no visible guns and guards but they were giving out coffee/biscuits/wine and cheese.
