(Don Treeger / The Republican) Facebook Share CHICOPEE — With any one of the COVID-19 vaccines you’ll get increased immunity from the deadly coronavirus, maybe a little soreness and now 20% off on food orders every Monday at Rumbleseat Bar & Grille. Rumbleseat owner Bill Stetson said this week he’s offering the discount for three reasons: to thank the health care workers who are his customers, have borne the brunt of the pandemic and are likely to get the vaccine; to recognize the senior citizens who are customers who are now eligible for the vaccine; and to generally encourage people to get immunized.
