Well, no, technically he's not looking at anything because he's blind. Snake is mightily tempted to fire off a choice remark to the stranger's stating of the obvious. He tempers it to "I'm trying to determine what kinds of bread are in this row without picking up every loaf and sniffing it through the plastic." He prides himself on being able to memorize the location of everything in a store. Unfortunately that involves trial and error in the beginning.

"Management was kind enough to give me a map but it's not as specific as I'd like." He also won't know how much everything costs until he tries to pay for it. Trying to determine what's cheap and expensive in pounds is going to be another chore.
