besamim / dunkin donuts

Question

2 quick questions Rabbi -- thanks in advance: 1) Can we eat at any dunkin doughnuts, even ones that don't have hashgacha if we only eat the doughnuts or bagels? Its such a big chain that it seems like it fall under the everything is the same in everyone except whether or not they serve ham sandwiches, which are separtae from teh donuts and bagels... 2) If you don't like the smell of the besamim for havdalah, and for the beracha in general, is that ok? thanks -- appreciate your help!!
