Play with your food; to add effect, act like it's a special performance for the people at the পরবর্তি table.
Turn around every thirty-seven সেকেন্ড to the people at the পরবর্তি টেবিল and ask them if your আসন is too close, if you're talking too loud, etc.
Whenever আপনি see someone getting up and leaving, bolt to their টেবিল and take the tip before the wait-person returns.
Eat REALLY loud; make disgusting noises; slurp EVERY time আপনি take a sip of your drink.
Constantly re-adjust the positions of absolutely EVERYTHING at your table; seats, silverware, dishes, the টেবিল itself; and make sure to make a big production out of it.
Order something on the menu, preferably something very specific, then when it comes, claim it's wrong and আপনি ordered something simple. Make a big production about the ineptitude of the help.
If shells are on the menu, order them and take them home. Come in the পরবর্তি দিন and say, "Those shells আপনি sold me jammed up my shotgun! I want my money back!"
As soon as someone at a nearby টেবিল gets up, jump into their আসন immediately, and claim you've been there the whole night. This is especially great when the others at that টেবিল are in on it.
Whenever anyone leaves their আসন at another table, put some particularly messy peice of খাবার on their seat.
Two Words: খাবার Fight.
Poke the person পরবর্তি to আপনি repeatedly with your fork. If they try to retaliate, curl into a ball and start crying for your mother.
This only works if the person has their back to you. Select a single strand of hair from the person's head and pull gently. When they reach up to touch their hair অথবা try to turn around, look at the ceiling অথবা pretend to read the menu. Repeat constantly.
Tap your fingernails on the টেবিল top, ignoring any evil stares that come your way. (This works anywhere, not just restaurants.)
Hug yourself and rock backwards and forwards in your আসন whilst muttering incoherantly. This will not only completely embarrass those at your table, it is also extremely annoying.
Help yourself to other people's meals. If they complain, pretend to stick your fingers down your throat and ask them if they'd like their খাবার back.
