Tuncay stormed down the tunnel after being substituted during the weekend defeat to Bolton.
It was the third time this season Tuncay had reacted to being taken off and his actions did not go down well among the Britannia faithful, with some jeering the Turkish star.
Pulis believes Tuncay could face a similar reaction from his team-mates as he has built Stoke's success in the Premier League on team spirit.
"Players have egos, and players, especially from abroad and from different cultures, have different ways of showing their emotions," said Pulis.
"You have to accept that, but whether the lads do or not, he has to stay in that dressing room."
He added: "I can understand the crowd (booing). This club has been very united over the last few years, the group of players and supporters together and I think they appreciate it if the team is having a go.
"Tunny is different but he has to go into the dressing room and face the players afterwards. The lads won't be too happy, irrespective of where he is from.
"They have got this spirit which is very special and they expect him to be the same."
However, Glen Whelan insists his Stoke team-mates do not hold a grudge against Tuncay.
"Tuncay was disappointed at being taken off. But he'd run his heart out," said Whelan. "The manager felt he needed some fresh legs. He'll be disappointed, too, at his reaction.
"But we're all feeling a bit frustrated. That was a game we should have won. We created so many good chances, hit the post twice and there were one or two amazing misses.
"Then we had a lapse of concentration towards the end and got punished for it."
