You are so lucky to have a Wawa!
I learned about them when we did our mod meetup in Philly and I got stranded. I was able to put together breakfasts and lunches just from stuff at the Wawa...they have all kinds of healthy stuff...tuna salad, hard boiled eggs, cheese sticks, water, etc.
I even splurged on a small pint of SF ice cream to drown my sorrows and getting stuck for an extra day on my own.
Flavored coffee is fine as long as the flavoring is part of the coffee beans or comes from sugar free syrup.
What I'm wondering is if the 'flavor shots' at Dunkin Donuts are kosher? They look like they might be like extracts...but I'm not sure from their website. Might have to go in and ask someone.
