text: Prior to tonight I would had several great experiences at Mac Shack Tonight ruined any chance of my return to the restaurant The young lady working the register told me that the owner will not allow any substitutions or changes in their prepackaged pasta dishes When I asked why as I would had it done before without any argument from the staff she walked away and got another young man to come over and tell me that the owner used to allow it but now really does not like it and they cannot do it When I told them that I would just find somewhere else to eat and I did NEITHER of them made any effort to retain my business It is not like I was asking to add ingredients to a dish without being charged or cheat the system I just do not like shrimp or jalapenos in my pasta but LOVE the rest of the dish I did not think it would be too difficult to accommodate a simple request like substituting one vegetable for another but hey what do I know I would not be shocked if other loyal regular customers find elsewhere to dine as well Disappointing really
