Is it a red flag if the caterer takes 1-2 weeks for responding?

So we have been trying to work with a caterer over the last 4 months to work out a quote, menu, and plan. When I told them I was going to be in town only for a couple weeks in June (I live abroad, so emailing has been the main communication method), they didn't respond fast enough for us to be able to make a decision about catering during the trip. Even when I emailed her saying we were interested in moving forward, she still took over a week to respond to us. The response rate is usually 7-14 days, but we like this caterer the best on our venue's approved caterer list. Should I take the slow/poor communication as a red flag? I am wondering if the communication timeliness will improve when the wedding date comes closer (summer 2022) and if anyone else has experienced this?
