how to deal with a difficult customer in a retail store

General frustration is difficult to deal with when everything seems to be going wrong.
Viruses use their host's metabolic enzymes and some viruses mutate very quickly so they can easily become resistant to drugs. Viruses are almost biologically inert until they infect a cell.
The viruses are not living in simple condition,but when they get host cell or host organism they come in alive form and be active & reproduce.The viruses contain strong coated wall around them made of proteins called "Capsid"which is very difficult to destroy.This Capsid contains special materials which penetrates the host cell's wall and make RNA or DNA(genetic material) of viruses entered in host cell.Different types of viruses contains different type of Capsids and it is very difficult to deal with them.Note:- Some bacterium contain "Restriction enzymes" which stops duplication of viral genes and thus make viruses ineffective to them.
It's not that other people are difficult to deal with, it's that we don't want to change to work with them.Because everyone is different.
It is difficult because viruses lack the ability to replicate themselves and theey lacks energy metabolism and other pathways that living things have. Viruses are totally depending on their host. If they want to replicate, they have to infect the host.
It was difficult to deal with but he until his arm healed, he would have to do so.
