I really looked forward to going to Ithaca Bakery ...

I really looked forward to going to Ithaca Bakery for the first time. I was visiting Ithaca. This was on either 10/10/19, or 10/11, early evening. I wanted to eat dinner and have a glass of wine. I walked in and stood at the counter. There were three staff persons behind the counter and not one of them even acknowledged my presence. One, a man who was restocking the drink cooler on the far right side of the bar, made eye contact with me and still did not acknowledge me in any way. He then proceeded to wait on a man who had just walked up to the counter. I waited for nine minutes like that and then walked out. Im not even an impatient person and this staff behavior felt disrespectful to me.
The baked goods looked incredible but if staff do not know enough to greet you and wait on you what good is great food?
(I am 66 years old. Was this agism?)
Years ago, I worked in the restaurant business as a server for over ten years. To treat customers as though they are not important enough to even acknowledge is very bad practice. Even if a server is busy, say hello with a smile and let customers know that you will wait on them as soon as possible. Is that too much to expect?
I was seriously dissatisfied with my experience at Ithaca Bakery.
