i am curntly in possesion of a variety of items that require their packaging opening i order to liberate their contents

but

i am also at the disadvantage of being alone in the office as well as being hampered by the fact i only have one useable hand in with to facilitate the freeing of said contents

so any ideas on how to open a gottle of lucozade with just one hand?

or a bag of crisps?

or the sandwich i bought yesterday?

i nearly had to wait for assistance yesterday in order to go for a pee as i couldn't unbuckle mt belt or unbutton my trousers (the wife reattached the button last night nd i m wearing more suitable atire today to lessen the chances of this happening again)

thank you for reading and please don't move it to the muppet room, i am after serious input here
