I remember going out for a meal with 4 other couples. One couple decided that they didn't want anything. As the courses were served they picked at everyone else's meals. When the meals were finished, they got up and left the restaurant without offering to pay. Needless to say, they didn't get invited out again.
You'll be fine, Melv.......unless two OFSTED inspectors join the party....but even then they will sit at the back of the restaurant with sour faces and clip boards wondering whether or not to put your table manners into special measures......☺
