Just this week I did my first price audit at a liquor store (not for iSS) and most of the products were high dollar and behind a counter with a cashier right there. I ended up breaking the shop up into two days because I felt like after just a bit I was seemingly very conspicuous/weird. There was a different cashier the next day but in addition to that, even with my glasses the price tags were so hard to see from afar. I think that's the last one of those type shops I do!
