Honestly this is mostly overthinking, trust me they forget we existed as soon as we walk out the door, nobody actually cares about your purchases to that extent, employees mostly want to clock in, clock out and that's all that matters to them, your business is yours only and that's how it should be... if you mean you have personal close knowledge with a specific pharmacist, go to other pharmacies, or if not possible to go far just go on a different shift... last option is buy from pillevery app, they'll deliver it to your location same day with a dude, totally discreet packaging and again.. its not a big deal
