You are, of course, well within your rights to increase the portion size. In fact, most customers would probably be pleased by this, since most Americans are more interested in filling up than they are in paying for traditional portions that are meant as a tide-me-over.
However, you shouldn't be suprised when someone says your sandwiches aren't traditional and/or that you aren't the best spot for traditional
Personally, I think I would say the same thing if I ordered a tea sandwich and got something back that wasn't dainty. That's not to say I wouldn't go there. Just that I wouldn't go there for traditional tea (instead, I'd go when I wanted a full meal with my tea).
And, if you reacted like that to my review (insulting me by suggesting that my opinion on the flavor of something was wrong, or that I hadn't even tried it), I would just stop going altogether. That kind of sarcastic ridicule isn't going to win you any customers.
If you can edit your reply on TeaMap, I would suggest doing so to remove things like "these are about as 'traditional' as you can get" and "If she refers to the mere concept of a Roast Beef & Asparagus sandwich as being 'gross', well, that's more of a personal preference." Just stick to something like, you have traditionally-made sandwiches in larger sizes, that you are sorry she had a bad experience, that the roast beef is one of your best sellers, and that you would welcome any suggestions she might have to make her experience more pleasant.
Just my 2 cents.
P.S. I tried to look at your web site, but it appears to be down at the moment. If you haven't done so already, I would suggest posting your menu to your web site, along with pictures showing the size of your sandwiches. This will help manage customer expectations. And, of course, be sure to provide links to any good reviews you have received (like http://www.suburbanchicagonews.com/beaconnews...
