Ok,Iam an intern pharmacist,i practice mainly in private pharmacies,however once a month I do visit my local hospital

So,I wonder how could I approach doctors tho?,as pharmacists we are not allowed to leave the pharmacy,so the best chance is during the morning(8am) when everyone comes to work,but this is uncertain and requires me to be very quick,as they dissappear within 3 minutes (short hallway),plus people mostly rush,makes sense

What are your strategies?
