I am angry waiting in the chemical hose for a minute, I propose that chemical engineers should have chemical "Filled" barrels" instead filling chemical barrels time to time. I am not a patient guy. For an example. the medics can purchase blood, and for the Weapon modifiers can use the blood swep. They Weapon Modifiers need to wait a minute and that is time consuming. So people tend to purchase blood from the medics' f4 miscellaneous . Do it for the chemical engineers. thank you.
