Input: Text: so i work as a salesperson in a mall, and today has been a rough day as i hurt my back. i've been spending a large amount of time sitting down on the benches on our sales floor. 

so here i am browsing away reading the post about cleaning dildos and a customer walks in. i talk to then about stuff and they notice i have a nexus 6. he asks politely if i would mind showing it go him. i graciously hand it over and he unlocks it, which opens to the post. 

the guy was a bit older, probably mid 40s (i was surprised he even knew what the phone was) and seemed a bit more proper than most. i watched as his eyes glanced down the screen and his face morphed from excitement to an obvious wtf. he hands me my phone back after maybe 10 seconds and smiles the most awkward smile i've ever seen, thanks me and walks out. as he just about exits earshot i hear him speak to his wife and say "let's not shop here anymore"
