A spokesman said the male who was believed to be intoxicated proceeded to enter the store through the drive-in window.
"Members of the public assisted staff in getting the male outside the store and a scuffle broke out as they attempted to get him to the ground," he said.
"Police arrived a short time later and spoke to those involved.
"The male has been trespassed from the store as a result and there is no further action at this time."
