Absolutely terrible. I know A&W usually isn't like this, because the many other locations I have visited were all just fine.
We ordered 2 sandwiches without tomatoes, to go. When she handed them to me, I asked her, "Are there tomatoes in this?" She confirmed that they did not have tomatoes. When I got home, they did in fact have tomatoes. Not even a big deal, we just took them out; disappointing nonetheless.
My burger had a hair in it. I know it didn't belong to me because my hair isn't a foot and a half long. The burger made me mildly ill, and my brother's made him severely sick. Worst experience I've had with any A&W. I won't be going back, and I suggest take your business elsewhere.
