I will preface this with the statement, I usually do not like Giant Eagle. My experiences at this particular Marketplace store, however, have been above and beyond my expectations of a grocery store.
The employees there are exceptionally helpful. One day, I was navigating the aisles with a stroller in one hand and a cart in the other, trying to find a particular product. I couldn't find it where it usually was. A gentleman approached me and asked if he could help. According to him, the entire section had been moved. So I thought her would just tell me where it was and leave me to it, but he actually helped push my cart to the section where it was. I thought this was very nice of him.
The prices are always kind of high (which is my main reason for not liking Giant Eagle in general), but this kind of service keeps me coming back.
