Mary Taylor (Patti Clare) is set to cause all kinds of bother in Coronation Street next week.

Warning: spoiler alert!

Mary stages a Greek night at Roy's Rolls, but things get out of hand when diner Beth Tinker (Lisa George) starts giving the guests shots of ouzo.

Roy (David Neilson) returns unexpectedly from the US and is furious to see what is going on in his café.

Things then go from bad to worse when a licensing officer from the council appears to investigate the illegal sale of alcohol.
