Hard Seed in Pot Belly Sandwich

Got a hard seed in part of my Pot Belly Sandwich today (second piece had refrigerated from yesterday). Potentially size of a Skittle that was startling. I called out a small bone in my Sushi a bit ago on this blog thus I figured it would be wrong to not comment on this as well. Might have been edible, my teeth aren’t great so I spit out the seed. Reminder I don’t own the product, company names. I like Pot Belly Sandwiches what to comment on is iffy at times.
