Roti Prata

I've never written a negative review about a restaurant/ hawker centre but today I'm writing one due to the service I got there. The Prata was crispy but they served me a butter Prata instead of cheese Prata and insisted it was cheese! When I tear the Prata apart, I could only see yellow liquid flowing out, and the chef wanted to change for us after asking me what I wanted and I said cheese Prata. But the waiter and the manager kept insisting that it's melted cheese and didn't allow him to do that. I've eaten enough cheese and melted butter in cooking to differentiate cheese from butter! In the end, the manager never apologized but offered another cheese Prata (obviously I never finish my butter Prata coz I didn't like it). And this one was butter PLUS cheese Prata, coz the manager was trying to cover the mistake by adding butter to it as well, but I could tell there's cheese this time as it's more salty. Don't think I'll visit the place again, sometimes money or food is not the issue, the attitude and experience are.
