Can I use a plastic fence in front of the pharmacy?

It is good to use a plastic fence in front of the drugstore. Every citizen who goes to the drugstore to buy medicine should scan the health code and take his temperature. Moreover, citizens and pharmacy staff are separated by plastic fences, and the walls are enclosed. Buying medicine, paying and taking medicine are all through a small window to reduce mutual contact. The pharmacy staff said that this is a double protection. Pharmacy staff are afraid of having the opportunity to infect the public because they contact too many patients every day.
