About 20 protesters were thrown out of the Boots branch in North Street, Brighton, yesterday.
They were taking part in one of a series of protests organised by UK Uncut to highlight tax avoidance by companies.
Sussex Police said that officers stood by as store security staff removed protestors from within the shop and from the steps outside.
There were no arrests.
Chief Superintendent Paul Morrison, who was in charge of policing the protests in Sussex yesterday, said: “The protests have been largely peaceful.
“We fully support the right of people to demonstrate peacefully and within the law.”
In a similar protest at the Boots branch in Lewes, five people were arrested.
