Extremely incompetent, process-obsessed people at this store who don't care about customers.
I called to ask if I could place an order for a gluten free sandwich on the phone, was told that I could only order online not on the phone, then I explained that there was no option for gluten free bread online. This took them a while to understand but eventually they said I would have to place an order online with the regular bread and then call in on the phone to request gluten free bread. So I went ahead and placed an order online. Then they said actually they'd need to check with their shift leader to see if they'd be able to do that and when they did they told me that I wouldn't be able to do this and could only get gluten free bread by waiting in line in the store. Eventually I was able to convince them to make a one-time exception but they warned me I could never do this (thing they told me to do) again.
It does seem like it'd be smart to let people get gluten free bread placing orders online and they're losing plenty of customers because of this, but ultimately this restaurant doesn't seem to care much about customers and mostly care about process.
I guess they figure don't need to care about customers because their food is pretty good.
Still, it's unfortunate short-term thinking to mistreat customers.
Update: it's not the people in the restaurant's fault. They try their best. The management hates innovation and treating customers well.
