On Monday NOV. 4 at 7:00 , I got a very delicious tuna sub at Grum's on Coventry. This purchase prompted me to return on Nov. 7 in anticipation of another delicious tuna sub. This sub was the complete opposite - mushy, devoid of much tuna, lots of mayo with no discernible chopped veggies. I called to express my disappointment and was met with an insincere "sorry". Why the difference in quality ?? It was clear that the person I spoke to didn't want my business!
