Twelve year olds in comic shops are savage, they don't even blink when they tell you your taste is trash. Been there, my guy. Best thing you can do is just ask them what they're reading and why, because half the time they actually know their stuff and the other half they're just parroting whatever YouTube channel they watch. Either way you walk out with something new to check out, and honestly that's worth more than the five bucks you came in to spend.
