While I understand that staff wear red shirts, who the heck is DEBBIE??? and why would you be covering for DEBBIE??? and why would this be regarded as a joke ?
The wife meant get a carton of milk AND if they have eggs get 6 eggs.... however the husband thought that she meant get 6 cartons of milk only if they have eggs in stock.... so he bought 6 cartons of milk because he saw that they had eggs in stock.
