Calm down. It's not like that everyone that had walked past OP would've gotten it, that's highly unlikely. It's perfectly 'safe' to just buy the shampoo in a store. Yes you had a bad experience with it, and I feel sorry for you but you can't just assume how someone acted.

While that's an unfortunate event that happened to you...we live in 2013 now and everyone knows that lice are actually attracted to clean hair because it's easier to move around in. When I was a kid I got head lice twice...and it is definitely an unpleasant experience. But this cashier still had no right to deny OP service like that. Does that mean the next time I have a bad cold and need cold medicine, I shouldn't be allowed to go into my local pharmacy to buy cold medicine but rather order it on Amazon...because I'm contagious? That is probably the most absurd thing I've ever heard. Not to mention as many others have said, this cashier had no empirical evidence that the shampoo was even for OP...but regardless of who it's for, the clerk had no right to deny his/her right to be in the store or buy the product. AT LEAST let OP buy the product and leave..being he/she was already there. As someone who's worked in retail for years, I can't even fathom how this was even allowed. But regardless...for you to actually agree with how this was handled and blaming OP for exercising his/her right to walk into a pharmacy and buy the necessary product. He/she wasn't causing any kind of disruption. You know, we as a society take the risk of contracting a cold or any other kind of condition everytime we step foot out the door and touch a doorknob or even come into contact with another individual. But we don't walk around in giant bubbles or quarantine ourselves from others. Live a little!

My eyes are bleeding from those walls of text XD @122 Yeah, because the OP is going to pay twice as much for the shampoo online (express delivery shipping) to get it days later and just sit there in the meantime suffering... I thought you said in your little story that it was a miserable experience? Why would you want them to prolong that? You were a victim and yet you choose to sympathize with the clerk, who discriminated against the OP because of their condition, not too unlike your abusers in middle school. Nice.

You act like the world owes you something. It's highly unlikely that anyone could contract lice from a person unless they were actually making direct contact with their hair. You even said it was over 20 years ago... suck it up and move on with your life.
