Me and my sister came today to buy food at dunkin donuts. We were last here last year in July. Today we could not enter the side by dunkin donuts unless we had a key. We were not guest but buying from dunkin donuts and needed to use the rest room. This has changed you never needed a key. This guy walks up while we trying to figure out why the door won't open. Asks if we have a key. We think he is a guest so we say no we coming to use the restroom. I tell him it was not this way last time we here and it turns out he is the manager of the hotel he bought it last year claimed he changed this a year ago (untrue we here 9 months ago). He said very rude we can't use the restroom unless we guest. We said we buying at dunkin donuts. To which he said we can use it but have to go around front. He claims the reason he changed it was everyone coming to use the restrooms and some one stole from their breakfast buffet. Once we did go inside it says you need a key to use the buffet how could you steal? No one questioned us coming in the front door. How does this stop his 2 issues? And why would random people come in go use the restrooms? Every time we come at least once a year we have only seen guest in here. Either way I would never stay in a place like this where the manager thinks he has the right to talk down to you. And make up wrong reasons to keep customers from using the only restroom in that area.
