[SoJustMe]

Before three weeks, I ( went to ) Macdonald's restaurant with my family to have dinner, but I didn't like the service there for many reasons.

.First, the food is unhealthy (which) often ( oily - fatty) and that (causes) many diseases to our bodies

Second, ( the ) services ( were ) very bad and slow becuase when ( we ) arrived ( to ) ( the ) restaurant

the waiters ( didn't ) take ( our ) order quickly, they let us waiting for ( a ) long time . Also the ( employees - restaurant workers ) ( were ) very slow ( while they were doing their ) job to serve us.
Finally, it was dirty.
